Kotlinbots: Building Your Own Personal Robot Army
summary
Builds real robots with Android Things + Kotlin, using Raspberry Pi / Pico Pi, GPIO for LED and button, PWM for servos and DC motors, and Kotlin coroutines for nonblocking blink and motion loops. Demonstrates an H‑bridge for motor direction, a phone-controlled vehicle via the Nearby Connections API (it connects, sends byte commands, and drives forward/back/turn), and uses drivers and a Rainbow HAT to expand sensors; continuous‑rotation servos and Adafruit PWM HAT solve the 2‑PWM limit for multi‑servo robots.
