Metal Detecting Robot

Electrical Engineering Student;

Built a Bluetooth-controlled robot using STM32 and EFM8 microcontrollers, H-bridge motor circuitry for movement, and a Colpitts oscillator for metal detection.

Skills: C, BLE, STM32, Circuitry, Motors

  • Integrated programs between an STM32 (transmitter) and an EFM8 (receiver) which communicated wirelessly via Bluetooth (JDY-40) to control a remote-controlled robot.
  • Constructed DC motor circuitry with an H-bridge and an optocoupler (for electric ground isolation), enabling robot movement.
  • Engineered a Colpitts oscillator to detect inductance changes in an inductor by measuring frequency shifts caused by the presence of nearby metal.
