Debounce arduino push button sketch Answered

Hi,
I have done the following sketch and wiring, i have tried all sorts of Debounce code in the sketch but can't get it to stop.
Most of the sketches i have read and tried switch the led on with one push and off with the second. i just want it to stay on while being pushed and go off while not being pushed, i am working towards RF or Bluetooth but not until i stop this bounce!

To properly troubleshoot this, start with only one arduino to get the switch to turn the LED on and off on the same board with the switch.

It does do that its just serial communication that seems to be the problem

crossed wires between two arduinos TX-RX, RX-TX, shared ground like MikeR3 suggested.

I dunno, maybe you have to tweak the delays from that sample code to allow it to communicate.

thanks for your help, i had to put a command in to go low if serialprint K was not there, also i needed a delay to ge e voltage p for some reason b all sorted now!

Also, run the program while looking at the serial monitor, whenever I set up a pull-up resistor switch situation, you can never be sure if it goes high when pressed or is low in its unpressed state. You can set up the switch using the internal pullup on certain arduino pins without the added resistor. Depending on the Arduino, it may return a value opposite of what you expect.
