I have looked through them twice. I suppose I need to begin with a simple course on Arduino. My Bittle came pre-assembled, but I need to calibrate him/her and I am quite tentative. The things that are taken for granted make me an "idiot" among the rest of you. I am starting this from scratch.
@David Baskwill Our controller board is compatible with the popular Arduino Uno. You can take some entry tutorial to get familiar with the system. This course may be helpful. https://www.yuque.com/tinkergen-help-en/bittle_course/lesson_2
