  • The first grove port of REKA:BIT will be connected to the potentiometer
  • Connect LEDs to the breadboard, where: The long leg (Anode) should be connected to the output pin. The short leg (Cathode) should be connected to a resistor, and the resistor will be connected to the ground pin. After that, connect the female wires coming from the grove port to the male wires on the breadboard
  • Connect both servo motors to the servo ports number 1 and 2
  • Connect the DC motors to their terminals

Step 4: Attach Components to Cardboard


Insert the potentiometer in the middle

Place the breadboard over the cardboard piece

Attach servo motors

Place DC motors on the bottom sides

Attach REKA:BIT and fix it using cable ties

Insert the caster wheel into a piece of cardboard and place it at the bottom

Place the battery holder over the cardboard piece

Make the circuit connection as shown in the previous step

Attach the ice cream sticks to servo motors

Close the top side with a cardboard piece slide10


Step 5: Code


Now, connect the MicroBit to your device and open MakeCode editor to start programming.

  • Add REKA:BIT extension and follow the code block in the picture above
  • After completing the code block, download it and compile it over REKA:BIT
