In this “differentially-steered robot” design, the Arduino is configured to control ... when the on/off switch is in “ON” state. And finally, the term “BOT” may be a little of an exaggeration here.

These components are the heart and soul of any robotic system, providing the necessary control ... the Serial Servo based on ESP32, the Serial Servo Pico HAT, the Serial Servo Arduino Shield ...

He connected the Arduino Mega’s LED output to a pair of LittleBits which then switch a servo between two positions. A bare servo wouldn’t be much fun, so [Outaspaceman] connected a tentacle ...
