I would like to know where on this circuit board I need to solder wires to connect to the raspberry pi GPIO pins.
This circuit runs on 2 AAA batteries currently.
The circuit is completed by a button press on the circle in the middle.
I was thinking about soldering on the ground point just above the circle in the middle and also soldering on the solder point on the VDD circuit just above the PWM1 writing.
This project is for video conferencing.
I would like to have my python program detect the button press and open a webpage.
I'm also looking to interface with an IR emitter to turn on a Sharp or Samsung TV.
Any help is appreciated.
