Hi there. I’m setting up a bubble machine toy to be controlled by a Photon. I’m very novice in electronics (I’m more of a software guy).
I opened the sucker up and soldered wires to the same points that are connected by a toggle button. I have my Photon set up in a breadboard with Tinker flashed on it.
I have tried putting the negative terminal of the batteries (with batteries in) into GND and the other end into D0, but it does not activate the toy. I can touch the two wires together to make the toy go, so the soldering is enough.
What’s the right way to set this up? Are the 2 AA batteries required, or can it take power from the Photon?
