I am following this build blog.
I had it working with alligator clips. Then soldered it all together and nada. I have taken it all apart and put it back on alligator clips and nada. I bought a new Teensy 3.6 and another smart shield and nada. Im used to using a chip that has some serial output to know what it’s doing. Would anyone have any debugging suggestions they could pass my way?
Edit: Here is the code
Thanks for your time,
