NOTE: We will use Serial Monitor (built-in) as the Virtual Terminal / Bluetooth substitute. if (cmd == "TEMP") Serial.println("TEMP:" + String(readTemp(), 2)); else ...

Every robotics project out there, it seems, needs a way to detect if it’s smashing into a wall repeatedly, acting like the brainless automaton it actually is. The Roomba has wall sensors, just about ...
