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.

Smart Information Station

Verified Doc 8/10 1300 XP
Evidence
This photo shows that the ultrasonic sensor is not detecting any distance as there is nothing in front of it so there is written 0cm.
Evidence
This photo shows how much temperature and humidity there is. This work is done by the DHT11 in my project.
Evidence
This photo shows that my LDR is detecting dark(because of the slightly dark environment and jumper wires above it ) and the status as hot because it is 32 degrees now.
Student Documentation

# Smart Information Station I made a Smart Information Station using an Arduino, DHT11, LDR, ultrasonic sensor, and an I2C LCD. The DHT11 shows the temperature and humidity, the ultrasonic sensor shows the distance, and the LDR tells if the room is dark or bright. The LCD shows all this information in different screens. I designed it this way so the information is easy to see and understand. I think it is useful because I can check different things around me using just one display.

I made a smart status system using an Arduino, DHT11 temperature sensor, PIR motion sensor, LDR light sensor, and an LCD. It shows the temperature, motion, light condition, and overall status like SAFE, MOTION, TOO HOT, or DARK ROOM all at the same time. This makes it easy to see what is happening in the room quickly.

Student Documentation

In this project, I connected an HC-SR04 ultrasonic sensor and an I2C LCD to my Arduino Uno. The sensor measures the distance of an object and shows it on the LCD in centimeters. I also used the Serial Monitor to see the distance values updating live. This project helped me understand how sensors can be used to make a digital measuring device.

Student Documentation

I made this project using an Arduino and a 7-segment display. The display has 7 small sections that light up in different ways to make numbers. I connected the sections to Arduino pins 2 to 8, and since mine is a common-anode display, the COM pin is connected to 5V. The Arduino then turns the sections on and off to show 0 to 9 one by one, with a 1-second gap between each number.

Student Documentation

I built a Smart Room Guardian using an Arduino UNO, LDR module, PIR motion sensor, DHT11 temperature sensor, LED, and passive buzzer. The system detects darkness and motion, turning on the LED when both are detected, while the DHT11 measures the room temperature and activates the buzzer when it rises above 30°C. The sensor readings are also displayed on the Serial Monitor, helping me learn how multiple sensors can work together in one smart system. Also it was like building some of the previous projects in 1 breadboard.
