This project enables the user to control an RC servo-based robotics arm wirelessly. The board is based on ESP32-WROOM 32E Bluetooth/Wi-Fi module, thus PS3 or PS4 wireless remote can be paired. The project is built using ESP32 chip with Bluetooth and Wi-Fi connectivity, 4 potentiometers connected to analog pins, 8 x 3 pin header connectors for easy interface of RC servos, operating power supply range 4.8V to 6V DC, LM1117-3.3V U1 regulator provides 3.3V to ESP32 processor, DC supply capacitor C5 helps smooth operations of RC servos, use a shunt to close the jumper J1.
ESP32 can be programmed using ARDUNO IDE. Example code provided to test the project. The user will be able to drive one RC Servo connected to the GPIO15 pin of ESP32. Use the right-hand side joystick of PS3 to perform movement of the RC Servo. more details about the ESP32 and PS3 interface are available here:
