Hello all,
I'm new to electronics and netduino. I have a netduino plus 2 and am enjoying learning. Thus far I've created my "hello world" with a red LED and a button to turn the light on and off. What I'm wanting to accomplish is opening my garage door via the wall switch.
The common wire in the wall puts out 25v with 3.6 mAmps.
What I've tried.:
3.3v power 820ohm resistor in Digital Output 7.
Push button control.
I'm also turning on the red LED.
I know that the code is correct what I don't know is if I have to somehow supply the full 25v to the receiving wire along with the 3.6mAmps in order for the signal to be sent to the control board?
I hope my question makes as much sense as it does in my head
Thank you
Dave
