Troubleshooting • Re: Sending 3.3V from one RPi to a second RPi's GPIO stops registering as HIGH when headless

In this project, the two Pis won't be able to be grounded together,
Why not? You've got wires going from one Pi to the other, why not add a 0V /Ground wire as well? Connect pin 6 on one pi to pin 6 on the other Pi and you're done.

Otherwise could you show a diagram of your wiring and explain what the problem is?
