Wait Until True

This tutorial walks you through using the wait until block to pause a project until a condition is true, using an LED Bumper as an example. By the end, you’ll have a project that turns the LED Bumper green once it’s pressed.

  1. Make sure your robot has an LED Bumper connected. See Configuring Devices if you haven’t added one yet.

  2. Drag a wait until block below the when started block.
