Use the glue gun to attach the left side


Attach the breadboard holder as shown in figure 4


Make sure to leave a little space for the ease of wire connection


Step 3: Connection

  • 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 pieceslide10

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
