Requiered Materials

Hardware Connect

  • Connect the left wheel servo to P1 of the Ring:bit expansion board and the right wheel servo to P2.




Step 1

  • Click on "Advanced" in the MakeCode Drawer to see more code sections.

  • Search for “ringbitcar” and click on the ring:bit car package to add it to your project. (As below picture)

Note: If you get a warning telling you some packages will be removed because of incompatibility issues, either follow the prompts or create a new project in the Project file menu.

Step 2

  • Snap the on start block from the Basic and initialize the P1 port to left wheel and the P2 port to right wheel.

Step 3

  • Snap the light level from the Input. The car will move to the light source when the light level is greater than the defined value.
  • The car will spin around to find the light source when the light level is less than the defined value.
