This is a module to encapsulate I²C commands.
This module uses the RCWL-1601 sensor, a smaller alternative to the ubiquitous HC-SR04 that fits easily in the old 2-wire ultrasonic fischertechnik housing.
This is a module to control two encoder motors and two servos via I2C. It uses an Arduino Pro Mini clone and a DRV8833 board.
Designed for two triple common anode 7-segment LED displays, with multiplexing and minimal part count.
