I've got Bittle mostly assembled, motors connected, etc.The TestBuzzer and TestSevenRGBLED Arduino sketches work fine (I haven't tried the others yet).
Serial Monitor is set to 115200 and no newlines.However, when I compile and upload the OpenCat.ino sketch, what I see in the serial monitor is what I show below, with no intervention from me. Every time the "k" appears, the head servo twitches. When I type something in the serial monitor, it says "wrong key!".
