This example of a Bluetooth-controlled car created with an Arduino UNO, a 25-gram board, can be dropped to seven grams with a Nano and even lower to five with a Nano Every in its place.

The build began as a simple two-motor, skid-steer RC car build with a fan for suction. Controlled by a smartphone app, a cheap Arduino board with an HC-05 Bluetooth module ran the show.

This iPad-controlled remote-controlled car provides fun for hours--but perhaps not for your kitty.

The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.
