Hi. I have got my Wixels up and running with an Arduino shield. All is working as promised, but I have a minor query.
The arduino is loaded with the Example Serial Communication Sketch (listen for H and L to turn the leds on and off). One wixel is on the arduino shield, the other is plugged into my Mac.
It works fine, but I have a minor issue, and I’d appreciate some enlightenment. When I open a serial terminal emulator (or otherwise open the serial port), the wixels communicate, and briefly the led on pin 13 flashes. Why? If I want to use that pin to say activate an alarm, I DON’T want serial communication triggering anything connecting to that pin.
Perhaps I should ask another way - which arduino pins can the wixel affect, and which does it leave alone?
I can’t seem to see an answer to this in the Wixel Shield document
