I’m trying to run the big Skywriter (not the HAT) with an Arduino Uno without success.
I installed the Skywriter Arduino library from github and tried the examples, but the Skywriter doesn’t do anything. There’s no error message, but Skywriter.onXYZ() or Skywriter.onGesture() are never called.
As there is very few instruction and no control LED on the Skywriter, I’m not sure if I connected everything the right way.
I connected Arduinos 5V and GND with Skywriters Vcc and GND, and the TRFR and RESET pins to Arduino pins 4 and 5 and declared them with Skywriter.begin(4, 5);.
There’s no word about the SDA and SCL pins, but I figured I have to connect them to the SDA and SCL pins on Arduino. But still no reaction at all. The serial monitor shows that Skywriter.onXYZ() is never called.
What am I missing? Or is it broken?
As I said, I miss the manual. Especially about hooking it up with an Arduino. I don’t even know which side of the Skywriter is the sensor side.
Thank you for helping,
