Microcontroller interface to Relays by ULN 2003

[milabut]

9 is +ve 12 volt and 8 is ground ie -Ve.The software assumes 8 as ground so it is not shown

[MrXtronnick]

You have number 9 pin as common ,but is connected to 12V ,so where is ground from 12v? or which pin of the IC is the ground??

[milabut]

I don't understand this .Pls write in English

hola me podrias dar una mano con un sintetizador korg m1 prende pero no carga la programacion tengo todos los diagramas y como puedo reducir 6 volt a 1.5

[3deeguy]

The simulation software is Proteus? That is a handy tool.

I am very happy to see the vidoe Microcontroller interface to Relays from you, hopefully the others also are happy for You

[Mjhond]

I am very happy to see the vidoe after you give this How to interface relays in Microcontroller output.Please note although in audio it is said that the IC ULN2003 has inverters it is partially correc

[anakmudajaman]

I Love The Video It Can Increase My Knowledge For example input high delivers output low but input low though gives logic high ouput but it can not be used for any purpose as the ouput is in fact open endeded

[NganaJHone]

Steady I Really Like This Video For example input high delivers output low but input low though gives logic high ouput but it can not be used for any purpose as the ouput is in fact open endeded

[willamricard]

Good, I like that you share this video, I wish success always example input high delivers output low but input low though gives logic high ouput but it can not be used for any purpose as the ouput is in fact open endeded

[milabut]

Input low can result at output high if you pull it up by a resistor

[AntoMelta]

Nice Video That You Share , So Very Nice Thanks You .For example input high delivers output low but input low though gives logic high ouput but it can not be used for any purpose as the ouput is in fact open endeded

[imegatrone]

I Really Like The Video From Your How to interface relays in Microcontroller output.Please note although in audio it is said that the IC ULN2003 has inverters it is partially correct

[bundawartini]

Your Video Is Very Useful Sharing For example input high delivers output low but input low though gives logic high ouput but it can not be used for any purpose as the ouput is in fact open endeded

Logic conditions that come from a programmed microcontroller.

[desmondappiah]

what component is the logic 0(in blue)

[milabut]

Interface is 5 volt from any ckt. But 12V is for relay drive.Pin 8 is -Ve .In this simulation software -Ve is asumed to have been connected at pin 8hence not shown

[josngmakina]

+12v supply,where did u connect the negative pole?with 12v relay what if the interface produce 5v only?

[adithyadeepu]

can you say which simulation software is used

[joset1996]

@adithyadeepu the software used is PROTEUS

[johnnytheprick]

tork about a cure for insomnia.

[munzzz123]

wat kind of relay did u use??

[joset1996]

@munzzz123 it's a component  called RELAY used with PROTEUS software. Is a relay of 12 volts. best regards.

thanyou thankyou thankyou, yaha
