Knowing how to make your robot travel specific distances with the Move Block is great, but, what if you didn't have to know specific distances to travel at all?  With Sensors, your robot can detect objects, sound, and light around it, and use that information to find where to go and what to do instead!

We are going to start by using the Light Sensor.  When we are comfortable with programming the Light Sensor, we will try out the Ultrasonic Sensor in Learning Mission 4.

The slideshow lesson below will show you everything you need to get started with programming with sensors.  When you are done, try out the Learning Mission 3 Worksheet and see how you do!
