Virtual Challenge 1: Touch Sensor

Challenge 1: Touch Sensor

Lesson Objectives:

To learn how to use the Touch sensor with a variety of output devices

Keywords:

Sensor: A device whose purpose is to detect events or changes in its environment and send the information to other electronics (EV3 brick)

Introduction:

Head over to 'https://makecode.mindstorms.com/'. This programming environment will be used over the coming weeks to improve your programming ability.

Main Activities:

Task 1: Touch Sensor and Motors

Create a program so that when the Touch Sensor 1 is pressed, it runs a motor at 75% power. When Touch Sensor 2 is pressed, it stops the motor.

Task 2: Incorporate the EV3 screen

Add blocks to the program so that when the motor is running, there are 'open eyes' on the screen. When the motor is not running, the eyes are closed.

Task 3: Add a motor

Add a motor to the setup. Adapt the code so that when Touch Sensor 1 is pressed, both motors run at 75%, however they must run in opposite directions. When Touch Sensor 2 is pressed, the motors change direction.

Task 4: Add Loops and Variables for intermittent movement

Add loops and variables to your code, so when the motors are running, they are stopping and starting every 500ms.

Below is a hint to get you started.

Extended Activity:

Can you change the code so you only need 1 touch sensor?

Rounding up the Lesson:

Take a screencast of Task 4, demonstrate it working. Make sure you show your code and your device performing it's task.
