Lesson 9 Worksheet 9.3 – Automatic lights

Write the following program to have the Edison robot turn the two LED lights on when it gets dark.


Drive the robot through a tunnel or under a couch and see the front lights come on.

In this program we are using the ‘less than’ (<) symbol to determine the path of the program. If the variable Light_Level is ‘less than’ 100, then take the true path and turn the LEDs on.

Experiment with the value (100) in the If icon.

What happens if you make it lower?

Heads up

The Australian Federal Parliament has passed a law that extends goods and services tax (GST) to low value imports of physical goods imported by consumers from 1 July 2018.

This means that all customers purchasing Edison robots and accessories with an Australian shipping address must now pay GST. The GST will be automatically added to your purchase and show as a line item on your invoice.

We've detected that you are in Australia, so we wanted to let you know that we have changed your settings to view our Australian site, which displays GST inclusive pricing.
