Sensors & Modules

These projects add external hardware to the micro:bit. Each page lists the parts you need, a wiring table and any helper library you must copy onto the board first.

Edge connector breakout

Pins beyond P0, P1 and P2 (like P13, P16, P19, P20) are only reachable through an edge connector breakout board.

DHT11 Sensor Read temperature and humidity from a DHT11 sensor. Intermediate IR Receiver (Remote Control) Decode signals from an infrared remote control with an IR receiver. Intermediate LED and Buzzer Turn an LED or buzzer on and off from pin 0 with button A. Beginner OLED Screen (SSD1306) Print text on a 128×64 SSD1306 OLED display over I²C. Intermediate PIR Sensor (Motion Detection) Detect motion with a PIR sensor and sound a buzzer. Beginner Servo Motor Move a 9g servo between 0° and 90° with the micro:bit buttons. Intermediate Ultrasonic Sensor Measure distance in centimetres with an HC-SR04 ultrasonic sensor. Intermediate
