ButtonA = 1pin to 10ohm resistor to ground + pin on board, 1 pin to 5V
Having a similar issue and I am very new to this. I have same type buttons/switches (Normally Open), though I want to connect 4 of these to a Teensy 2.0 board. What kind of connection would I need?I have read some other postings and they say this:ButtonA = 1pin to 10ohm resistor to ground + pin on board, 1 pin to 5VButtonB = repeat similarButtonC= repeat similarButtonD= repeat similarIdeas?
It's simpler to connect each button between ground and an Arduino pin and enable the internal pullup resistor, as I said before.
PS - I should have said don't use digital pin 0, 1 or 13. Any other pin will do.
