Use Your Lights!


mBot has a set of two LEDs that can be used for all sorts of useful (and fun!) purposes. In this activity, students use the LEDs to mimic brake lights, turn signals, and emergency flashing lights.

NOTE Unlike previous activities that include step-by-step directions, this activity is a set of coding challenges designed to engage students' creativity and challenge their coding skills. The challenges are intended for students who have done the previous activities or already have some familiarity with how to program mBot using the mBlock Blockly app.


  • Learn how to control and change color of the mBot LEDs.
  • Practice writing code for mBot to complete a task (brake lights, turn signals, emergency vehicle lights).
  • Troubleshoot coding issues when problems arise.
