Hello everyone, I'm very new to arduino and I don't know anything about coding but I have been asked by a friend to make a device to control 3 different leds from 3 different buttons. The thing is that I want when the button is pressed, the led to turn on for half second and then to turn off. Like a doorbell. I found a code that works and I modiffied it but now I need to add 2 other buttons.I tried but there wasnt any result. If anyone can, please help!!!
You can find the code for one led in the attacement.
Thank's again.
