This week we will learn about program branching and Boolean logic operations. During this week, we will create a doorbell, a status indicator light, and an ultrasonic distance sensor, learning about Arduino’s Boolean logic operations.

Course Schedule

Lesson 8: Doorbell: Logical Judgment and Digital Input

This lesson uses the doorbell, which is commonly seen in daily life, to introduce the program branching structure and how to obtain digital signals.

The hardware used in this lesson includes: Arduino UNO, IO expansion board, buttons, and buzzer.

Lesson 9: Status Indicator Light: Boolean Operations

Program branching can add various interactions to the program. The previous lesson used the doorbell as a case to explain the interactive design of a program under a single Boolean condition. This lesson introduces Boolean operations to achieve more complex program logic, creating a status indicator light.

The components required for this lesson include: Arduino UNO, IO expansion board, LED light, and buttons.

Lesson 10: Ultrasonic Distance Sensor: Pulse Length Detection

This lesson uses the ultrasonic distance sensor to explain the principle of ultrasonic distance measurement and the use of an LCD screen based on the IIC communication protocol.

The hardware required for this lesson includes: Arduino UNO, IO expansion board, LCD display, and ultrasonic distance sensor module.

Course Assignments

All three lessons this week have accompanying assignments to be completed in “Assignments and Challenges”. The deadline is April 9, remember to complete them!
