Lesson Overview

Students will learn the following things: 

  • What is analog input and how to do it in PictoBlox.
  • What are evive’s Potentiometers and how to read their state using potentiometer () reading block?
  • Activity 1: In the activity, kids will move a mouse sprite using the potentiometer by changing the direction of the sprite.
  • Activity 2: Controlling the brightness of the LED using potentiometer.

Material Required

1 set of the following material per group of 3-5 students:
