We recently posted a video on this channel demonstrating how to build a remote joystick control for a robotic cart using an Arduino UNO, a Joystick breakout board with an nRF24L01 transceiver board, and an RF Nano board with a built-in nRF24L01 chipset. In the current video, we will further explore the use of a BLE App running on a mobile phone to control an Arduino Nano RP2040-powered robotic cart.
