While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies ...

as well as an output stage which does the DAC-ing from the Arduino’s PWM outputs, and some more filtering/amplifying. Two 8-bit PWM outputs are used simultaneously to make pseudo 16-bit ...

Using the Arduino microcontroller, we will explore some of the essential and useful electronic sensors (light, sound, motion, sonar, infrared, angle bending), powerful actuators (relays, motors, ...
