How-To Tuesday: Ping))) ultrasonic sensor

[desktopgeek98]

I got an Arduino UNO for Christmas and I love it! My first large project will use one of these sensors.

[MrCoonskin]

Does makemag have an ownership interest in the Arduino or something? Id like to see other micro-controllers.

[Coolnventions]

IS TERE A WAY I CAN USE THE LEGO ULTRASONIC SENSOR FOR THIS

srry caps, too lazy to chnage it

[desktopgeek98]

@Coolnventions You'd have to disassemble the sensor (which shouldn't be that hard, but you might not be able to use it for legos anymore) and find out which pins are which.

[abcxyz46]

what is the beam width of the signal that is sent by the sonar sensor? I meant, in what angle range the ultrasonic sensors work? Please help. I'm stuck with one of those :(

[elanticrist0]

0:59 not using them,... throw in trash

[SniperMetal1]

excuseme. what name is the cable to use to conect the sensor to arduino?

[ultrasonicflowmeter]

nice job

[nafativedec]

wtf is with this loud sound douring makemagazine intro!?

[TheLgcooks]

what happened to kipkay

[Ilovelazers]

I FINALY GOT AN ARDUINO!!!! ITS AWESOME!!!

[legoclockfreak710]

@Ilovelazers I totally agree with you!!! i got my arduino six months ago... best b-day gift i ever got!!! but im already learning and practicing advance code!!!!

[legoclockfreak710]

@TheDhezballah i would love to get the beginners kit... but the arduino itself was expencive enough...

[TheDhezballah]

@legoclockfreak710 I've got a friend who owes me some money so I will probably be using that to get the Spark fun beginners kit.

[legoclockfreak710]

@TheDhezballah FUN! ill probably get one later down the road... but for now all i need is the arduino and a couple leds!

[TheDhezballah]

@Ilovelazers @legoclockfreak710 What parts and/or kits would you reccomend a beginner to buy?

[roboter421]

where to buy in germany?

[tamyboy1]

i made one my self using arduino , check it out

[dorianmcintire]

The ultrasonic sensor is a “smart” sensor able to communicate with the host controller using variable-width pulses also known as pulse width modulation (PWM). Even though it is using only 1’s and 0’s the width or time period between these 1’s and 0’s is proportional to the distance measured. Microcontrollers can very accurately measure the time between these pulses with microsecond resolution.

[Slench101]

but you connected it to a digital pin...

digital is just 1 and 0, while analog is many more values.... how are you getting variable distance readings out of 1's and 0's???

[Doogles94]

you should put that on top of a servo, and have it scan the area around you

[HarrisonIncorperated]

@brandon14872 I don't know but some sort of coding on the arduino where it would display feet and inches on a LCD screen

[N0M4dIC1RST]

@HarrisonIncorperated I made exactly that program using a Ping and a BS2 MCU. I simply had to multiply the Ping echo time by 2260 for centimeters and 890 for inches (word values) while using a standard (20MHz) BS2.

[HarrisonIncorperated]

It would be really cool if you could some how make a code to transfer a mathematical term onto the arduino so that you don't have to use a computer!

[brandon14872]

@HarrisonIncorperated what kind of mathematical term

[TheArvind18]

Where is kipkay??

[SoundsFantastic]

Can the PNG))) be used with the iOBridge?

[22marauder1]

Nice explanation, but it would be nice to see it actually do something like send back distance data or play a variable pitch tone.

Didn't actually see it do anything.

[UnicyclePenguin]

@22marauder1

If you look at the bottom of the arduino environment after he opened up the serial monitor, you can see it giving back centimeters.

[2gogy]

what name have it that is conected pin with sensor?

[yokin128]

kipkay>househouldhacker

[MrMapflyer]

can thoses sensors be more accurate? say millimeter

[sush150]

I cant even install the arduino hardware on to my computer!

[jimmysonson]

when are you going to do another arduino 101

[rexnecis]

I love that you have like every arduino, lol

[ALZOMIR]

hi my friend...very great job...anyway...can I use this sensor to differentiate between object that I want to pick up or the obstacle that I want to avoid for the Autonomous Robot?

[HappymanSeven]

Could of done an example..

[Mou5Karma]

Yeah :D on a robot it would be like a sensor so when it gets to say 10 cm from the wall or object it turns :D

[94vujke]

you're more collector than a producer... but thks

[hussien1010]

i really have seen alot of guys here using ultrasonic senor ..however there is alot of senors and more cheaper such as IR and ....

the question is ..why those guys using ultrasonic senor rather than others ?

THANKS

[droid7627]

i wish i had that may arduinos and zb1(s)

[BLADENEVERFAILS]

thers 38 people who dont know how to do

[LeetMoviez]

ITS WALL-E!

[itzjoeyppl]

it looks like robot eyes...

[Mortltd]

can dogs hear the ping of the sensor?

[Knightmetal]

This might be a stupid question but the truth is, I'm not very familiar with microcontrollers. Can the Arduino be programmed in Java? I'm working on a project that might need this sensor and the Arduino, before purchasing this I need to make sure I'm doing the right thing.

[americaneagle791]

Arduino Program. File > Examples > Sensors > Ping.

A hell of a lot easier than having to find the webpage and copying the code and pasting it in if you ask me... ^^

[clintdavistv]

right on dude!

[TakronRust]

It's the Game Genie of PCB's.

[Nanovirus5995]

im Glad Kipkay is gone. You actually sound human. Love the videos!

[Armaangandevia1]

@Nanovirus5995 i like kipkay

[5005qwerty]

Hail satana!

[abulmagd3]

what is the rang of this sensor

[ecclipse]

Do you think is possible to attach it to the wall outside the aquarium sensor the fish in the aquarium?

[roofy2k]

shields are for nuuuuuuuuuuu000000000000000000­bbbbbbbbbzzzzzzzzzzzzzzzzzzzzz­zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz­zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz­zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz­zzz

[NutsandGuts]

@roofy2k wtf

[papababis]

DISLIKE.

[infamousbackupplan]

wheres kipkay? 

[Shakespeare1612]

That is really cool, but it's so HUGE. Are there any commercial devices that do the same thing but are squeazed down to tiny tiny, like 3 mm x 5 mm x 1 mm?

[fennecfanatic]

@Shakespeare1612 It takes a fair bit of hardware to make an ultrasonic range finder. About the smallest you're going to find is the Devantech SRF01, which is still around 18mm in diameter and 6mm thick.

[JdGiose]

@fennecfanatic i was looking for some names:)

[vanjastanic]

lol. that's all i have to say.

[HappyBombFilms]

I need to learn how to use an arduino, and I need to get one

[razsadeq]

can this be used for objects that are not conductive, say a cup of glass?

[MrCelloman21]

instead of the pdf  i got the code of the ping

[ldeath83]

would it be possible to a device on your sencer that translats the distance into a number of pins that extend out and touch a blind persons skin to let them know how far an object is from them?

[tbsys31061]

@ldeath83 yes

[Finnlander132]

@ldeath83 yes, I thought of the same thing a while ago. I found it hard to think of a way to make each pin move independently. Linear actuators are expensive and too thick. If you can find a cheap way around this problem please share.

[TheWaddleWaddle]

is it possible to program it to display a message that when a person gets too close to your computer it says like "step away"?

[djhesit8]

yes it is

[LooseLeaves728]

yeah

[psychofish25]

what's the difference between the analog and digital pins?

[grapes008]

the out/in put. the digital works with a digital signal and the analog works with an analog signal

[burri123]

hahaha

[djhesit8]

analog reads/writes a controlig.... can read distance, can control gear speed etc... digital has HIGH and LOW only... if HIGH 5V is going out, if is LOW 0V is going out :)

[jimmy43524352]

Actually, the analog is just input, you need to use the PWM for "analog" output. and LOW is ground, not 0V.

[cyrixproductions]

Plz make a video about lcd's :D

[armouredhen30]

Point?

[loriaer]

May you make a video about LCD displays? I have some doubts......Thanks!

[MuslimMujahed]

can i use it using my own circuit?

[djhesit8]

why not?

[8magic]

How would I get the output of the ultrasonic sensor to display on a seven segment display?

[Jamesonh20]

Does anyone know if therr is a link that shows how to make this exact same proto shield? Thanks !!!

[djhesit8]

you can buy it

[uut0]

how complicated will it be to make an arduino the drives and "looks" if there is soemthing in its way with the sensor?

[CharlestonChew03]

=O crazy! What language is the code written in, any one know offhand? Man that looks like you could do some really cool stuff if you knew your stuff! =D

[omlan]

i got a nano, it's better than an arduino dumilanove, the only thing is i made a protoshield socket for it so i can use a protoshield on the arduino nano

[nearsightedduck123]

the has a LOT of duinos lol

[psilokan]

Why does the theme song always have to be 3x as loud as the rest of the video? Drives me nuts!

Other than that, great video as usual! Been watching them all as I wait for my Adruino to arrive.

[revelartist]

Where's your website? I have a question

[castello29]

hello everybody..

Im using PING ultrasonic sensor in my project, but Im using DE2 Board to control it.

Anybody knows how to use it by using the DE2 board as the main controller? (may be in verilog or NIOS system ) Plz help me..

tq..

[AQHackAQ]

aduino seems easy

[alfinator07]

i have a macbook too :D :D

[taggerslife]

what happened to kipkay

[hikura]

I dunno but this is the Makemagazine channel on youtube, Kipkay was hosting a show on it. so this is some other persons video, who isn't really showing you how to make something from nothing.

[crazynoob11]

rape

[NullPoint84]

he's a faker

[TheDevlix]

@taggerslife i yhink he does the weekend project ones

[pastryhat]

@taggerslife he does weekend projects.

[bears7777777]

@taggerslife kipkay posts videos on his own channel

[226023]

@taggerslife its how-to tuesday, not weekend projects.... and it was in 2009....

[Logo3801]

@taggerslife personal channel. collins gonna break off soon too

[AdmirB15]

que???

[omlan]

Aurduino is a microcontroller Dumb Ass!

[myass225]

if you didnt want a rude answer you should not have posted a rude question.

[alkasao]

nice

[chevyman217]

lol

[Anonimus1111011]

This is cool

[KenshinRyuichi]

Mystery of differences between Radar and Ping Revealed!!! Ping uses Ultrasonic sound! While Radar uses Radiowaves! -Ping is cheap *Radar is expensive -Ping is for robotics *Radar is for the military -Ping is Simple *Radar is complex -Ping uses MCU's *Radar uses CPU's Radar is a complex system while Ping is just a sensor connected to a processing unit. Ultrasonic sensors are not like radar, it is like ECHOLOCATION!!!

[97273998]

Whats that ardwino thing?

[kaze4159]

arduino

[magemager0]

I still have yet to find a project I can do....

[Splooshiba]

i had this problem, first thing i made was a night vision camera, cos that was just hooking up LEDs

second was a laser spirograph, didnt need much understanding, just videos

[MasterSergeF18]

True that.

[chevyman217]

true

[Tibbon]

@magemager0 Why? These are all easily doable.

[MultiJohn12321]

@magemager0 FFFFFFFFFAILLLLLLLIIIUUUUURRRR­RRREEEEEEEEE

[Maker521]

@magemager0 same with me

[DrrrrrtySanchz]

can u post a video on how to make a back-up censor for a car? plz! lol

[b21492010]

are you sure they are using camtasia?

[listenUPeveryonee]

Im using this for one of my Arduino robots.

[RagedPWNLord]

What happens if you aim at the moon? =D

[bliss314159]

you will wake up the man in the moon because he can here ultrasonic sound!

[94thts]

The moon explodes!!!!!!

[b21492010]

what program are you using to record your screen? can it be used on Windows XP?

[mojsije1234]

awsome

[z3p3l1n]

i want an arduino mega, now.... =/

[SupermanorNot]

i touch myself to this vid

[Superjadi]

what is the range of the ping before it becomes inaccurate?

[Crakspyder]

it maxes out at about 3.3 meters

[nesdrawer]

your vids are 2 high quality it takes ages for it to load

[IBJ0N]

its probably your computer because it loads fine for me

[suckithardnfast]

Its fine to me. Maybe you have a slower internet speed

[nesdrawer]

huh pu huh how dare you my internet speed is fine wait let me look 1mb internet speed oh crap

[shadowtube567]

then dont use HD.

[coconuts739158426]

Arduino software

[Guyya93]

yay mac!!! and yea if i knew how i would put that o a robot but idk nything about MAKING a computer...

[rueljre007]

can that ultrasonic senor run on windows vista?

[coconuts739158426]

yes i can run on windows operating systems just download the software for windows

[petfood56]

thats awesome

[ccjack156]

you now what would suck if a bunch of nerds started talking about o wait NERDS no jk

[deafmonk19]

looks like the ultrasonic sensor for mindstorm nxt robot

made a room alarm and a rubberband shooter attached to it.

[AtomicClockwork]

Good on ya! That is pretty cool.

[cheesymark]

ur right deeswizle it dose look like a wall-e but how would u do an eve??

[Psytoxix]

Wow nice

[Suschestvo]

Almost a radar)))

[KenshinRyuichi]

It's sonar.

[fsm1982]

Radar?

[skierplaterandy]

no radar uses radio signals that bouce off things, this is using very i frequency sounds.

[VeXorian1337]

Tell me... from a personal opinion, is a IR reflective sensor BETTER than a ultrasonic one?

[girrrrrrr2]

ir sensors cant reflect off of matte or flat materials.... so not as good

[DarkBusterXYZ]

depends on the enviroment, infrared fails on certain light conditions (like the sun) and ultrasonic could be confused by certain sound frecuenses, the ultrasonic is more reliable for multipruse use

[VeXorian1337]

The sun spectrum is filtered if I recall correctly, as well as most interferences. The only possible reason NOT to use a IR distance sensor is because of a possible weak reflective ability of a surface. But the utrasonic sensor also has this problem. Perhaps a combination of both ultra sonic AND IR, would be the perfect setup?

[accaunt4o]

I don't think IR & ultrasound will fit with each other. i mean the Ultra has a bigger range. whereas IR a shorter one , so u would have to have the target in the "middle" to have it absolutely correct : )

[skierplaterandy]

thats why people have made systems that have a servo moving back in forth and it finds the walls at any angle.

[VeXorian1337]

You're implying parallel monitoring... I'm implying serial.. First we check with the ultra-sonic, then with the IR. It's a double check... The only object that won't be detected very well then, will be a black soft object. But I think this sensor works on a different principle than reflection of sound. Think it uses the doppler efffect. Anyways... IR is much faster and more efficient for short distances - i.e. sumo bots.

[94thts]

Umm no, it doesn't use the Doppler effect. It sends out an ultrasonic sound signal and wait's until it recieves the echo. And by measuring the time it takes from it sends the signal until it recieves the echo it can calculate the distance. Pretty simple.

[VeXorian1337]

Yeah ofc, but some also use the Doppler effect to measure velocity... like the sonar... That's extremely effective for sumobots!

[94thts]

Can you explain how that works?.. I know what the Doppler effect is and all but how is it used in sonar?

[VeXorian1337]

By monitoring the difference in the frequency of the reflected sound wave after a period of time, one can also measure the velocity of the object, relative to the receiver. delta f = (1 - Vsource*Vreceiver/c)*f0

[94thts]

The speed of an object relative to the speed of the sonar sensor, am i right?

[VeXorian1337]

Yes! You got it... but you can also check Wikipedia for extra info... after all I can't be too sure :-)

[MightyJustas]

I got ultrasound security system in my car like this, kewl

[DeeSwizzle]

Hehehe...looks like a baby "Wal - E"...the next project will be an "Eve"

[rukulathegamer]

hehe xD

[hlblade57]

awesome i always look for new projects with my arduino thanks

[baldes]

Arduino Italian open source ! proud of it !

[tomek123kotek]

i want wires like that

they look cute
