Lesson 1 Scribbler Lights Up
Why do robots have lights? What does it take to turn them on and off and show different colors? The purpose of this lesson is to explore how to how to operate the LED lights on the Scribbler with code in BlocklyProp. We will also learn about the science of power and light used in robots.
Time to Complete
- 1 hour for Hands-on Activities
- 2 hours for Optional Exercises
What We Will Learn
By the time you complete this lesson you should be able to:
- Create Blockly code to control the Scribbler robot
- Load and run a program on the Scribbler robot
- Program the 3 LED lights to turn on with different colors on the Scribbler robot
- Turn your Scribbler's lights on and off and make them flash
- Add notes to your code to describe what it is doing
- Explain the difference between incandescent and LED lights
- Explain the difference between DC power and AC power
- Describe wave properties of light and the electromagnetic spectrum
What You Need
- Scribbler Robot with battery charged
- USB cable to connect robot to computer
- Computer: PC or Mac to program the robot (with Internet connection)
- BlocklyPropClient software installed on Computer
