Raspberry Pi Zero, Arduino, and BBC micro:bit 9

Figure 9.1 BBC micro:bit, Raspberry Pi Pico and Arduino UNO
• Bluetooth Communication: use the micro:bit’s built-in Blue-
tooth capabilities to communicate wirelessly with other mi-
cro:bits or devices.

Arduino
• Simple Projects

• LED Blinking: start with the classic ‘Hello World’ of electronics
– blinking an LED using an Arduino.
• Traffic Light Controller: simulate a traffic light system with
LEDs to control the flow of ‘traffic’.
• Temperature Display: interface a temperature sensor and dis-
play the temperature on an LCD screen.

• Advanced Projects

• Home Automation System: build a sophisticated home auto-
mation system using Arduino to control lights, HVAC systems,
and security.
• Quadcopter/Drone: create a drone using Arduino for flight
control and stabilization.
• Gesture Recognition System: implement a gesture recognition
system using sensors and machine learning algorithms with
Arduino.

Figure 9.1 shows a BBC micro:bit (on the far left side) plugged into
a 4Tronix bit:bot XL robot and programmed to control the movement,
follow lines or – by adding an ultrasonic distance sensor board – avoid
obstacles. The robot can be remote-controlled wirelessly if an addition-
