Microcontrollers - AVR Atmega32 - Understanding Button Debouncing

[MrAlexthemachine]

Okay I have a quick question. Wouldn't a rectifier diode work better for dealing with the reverse voltage caused by a switch?

noob question here.

Can i use any micro controller with the programming language that you are using?

(with a different programmer) and if i'm right the micro controller is enough of a resistor to not short the circuit right? since you connected the button to ground.

Man I love how fast you can draw!

[somebody301]

yes, in fact if you wish to see if there is a signal you can put a led + a resistor......

@somebody301 Good tip.

Another good investment is a logic analyzer. I actually have one of those and it's great to see if serial communication is actually happening. They usually come with many leads to probe multiple legs. I may get into that in the uart tutorial. A good project may even to create one from scratch and show the result on the LCD. Hmm!!

[somebody301]

@anajonesr sounds great.... but another project would be a ac/dc pannel amp meter, whit lcd display. Ac amp meters are very unusual, and if you find one it'll cost a lot of money, so remember to put some fuses if you are going to make it.....

[somebody301]

oh really? so it's better to wait..... ok thanks.

[anajonesr]

@somebody301 Yeah, I wouldn't invest in anything until you see a need for it. Even an oscilloscope is handy but not an absolute necessity.

[somebody301]

so a pc oscilloscope is less than $400. it's fine. What about wave gen? Do you know any cheap brand?

[anajonesr]

@somebody301 I don't use a wave generator... yet!

[somebody301]

Hi, what oscilloscopes were you using?

[anajonesr]

@somebody301 I'm using a cheap Owon oscilloscope. I hear that PC scopes are a great alternative.

[somebody301]

@anajonesr yes, but you have to spend also a lot of money for having something good. I'm saving money for trying to take an agilent DSOX2002A at 70Mhz or maybe if i can a 100Mhz(i chhose it because they have an integrated wave gen) but i think at this rate it wold take a life. How much is this brand cheaper, and did you had any trouble?

[anajonesr]

@somebody301 the PC versions are actually less expensive than what I bought and have better features. The Owon that I purchased was around $400.

very interesting! someone told me that there are free classes on microcontrolles at my univesity. after watching a few of these vids i will definitely visit them!

What camera are you using?

[anajonesr]

@josepaul2000 Canon Rebel T1i.
