Module 1

Welcome to Arduino

Welcome to your first step into the world of electronics.

In this module, you will learn how to use an Arduino Uno, connect components safely, write your first program, and build confidence using a breadboard.

You do not need any prior coding or electronics experience. Each challenge takes only a few minutes. By the end of Challenge 10, you will have completed your first electronic projects completely on your own.

Challenge 45

Display Sensor Values

Verified Doc 9/10 1090 XP
Student Documentation

The LDR measures the surrounding light intensity and sends the value to the Arduino.The Arduino displays the light value on the 16×2 I2C LCD.I made a silly mistake.
