Count-by-Count Activity

Introduction

This activity is intended to provide additional practice with using the touch sensor by completing a simple task. Students will build a small servo “gate” regulating the entrance into an area. To raise the gate, the touch sensor must be pressed, but once a max number is pressed no more entries will be allowed.

Consider pairing this activity with students building a diorama of their gated area. Examples might include a museum, lunch room, theater, or store. This lesson may also be tied with classes introducing CAD, or safety and accessibility standards for buildings.

Covered Concepts

• Touch Sensor

• If/Else logic

• Loops

• ElapsedTime

• Servo usage

• Programming angular limits on a servo with the SRS Programmer

• Intro to Robotics V2 - Unit 4, Lesson 25

• Intro to Robotics V2 - Unit 5, Lesson 29 (ElapsedTime)

Students will:

• Utilize the touch sensor in a practical scenario mimicking a real-life use case

• Practice programming a touch sensor

• Create a program that uses a count to track how many times the touch sensor has been pressed and that uses a timer to reset once the max is reached
