In this project, I used an Arduino Uno and an L298N motor driver to control a DC motor. The motor is connected to the OUT1 and OUT2 pins of the L298N. The Arduino sends signals to the motor driver through IN1, IN2 and ENA. I programmed the motor to turn ON for 2 seconds and then turn OFF for 2 seconds. This process keeps repeating automatically. Also it took me more than 2 hours to complete

I built an automatic system using an Arduino Uno, HC-SR04 ultrasonic sensor, and a servo motor. The sensor detects how close an object is, and when it comes within 20 cm, the servo opens to 90°, otherwise it stays at 0°. I learned how to connect sensors and servos to Arduino and use code to make them work together. I tested the system by moving objects closer and farther away and checking that the servo responded correctly.

### Documentation This project uses an Arduino Uno and a servo motor. The servo is connected to digital pin 9. The program makes the servo slowly move from 0° to 180° and then back from 180° to 0°. It moves one degree at a time with a short delay, making the servo move smoothly. This process keeps repeating.

### Documentation This project uses an Arduino Uno, a servo motor, and a potentiometer. The potentiometer is connected to A0 and the servo is connected to pin 9. When we turn the potentiometer, the Arduino reads its value and converts it into an angle between 0° and 180°. The servo then moves according to the angle of the potentiometer.

This project uses an Arduino Uno and a servo motor. The servo motor is connected to digital pin 9. The program makes the servo move to 0°, 45°, 90°, 135°, and 180°. It stays at each angle for 1 second and then moves to the next angle. After reaching 180°, it starts the same movement again.

# 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.

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.

In this project, I connected an LDR, a potentiometer, and a DHT11 to the Arduino. I used the Serial Plotter to see their readings as live graphs. It was fun to change the light, turn the knob, and warm the sensor and watch the graphs change. And I knew when the project was complete when I changed the knobs continuously, and the line on the graph went up and down

I connected an LDR sensor to an Arduino Uno and an I2C LCD. The LDR detects the amount of light, and the LCD displays the light level, such as “Light 642”. I learned how sensors can collect data and how an LCD can display that data. The challenge is complete because the light level changes when I cover the sensor or shine a light on it.

I connected a 16×2 LCD with an I2C backpack to the Arduino Uno using SDA on A4 and SCL on A5. I used the LiquidCrystal_I2C library to control the LCD and displayed “Hello Zero2Maker” on the first row. The message stays on the screen while the program is running.

I programmed the seven-segment display to count down from 9 to 0, with a 1-second delay between each number. When it reaches 0, it waits for a short time and then starts again from 9. This keeps repeating automatically.

I made a simple number counter using an Arduino, a 7-segment display, and a push button. The display shows numbers from 0 to 9, and every time I press the button, the number increases by 1. My display is common anode. Also after 9 the digit changes to 10.

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.

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.

I built a temperature and humidity monitoring system using an Arduino UNO and a DHT11 sensor. The DHT11 measures the surrounding temperature and humidity and sends the data to the Arduino through its OUT pin. The Arduino then displays the readings on the Serial Monitor every 2 seconds.

I built a PIR motion detection alarm using an Arduino UNO, PIR sensor, LED, and passive buzzer. The PIR detects movement and sends a signal to the Arduino, which turns on the LED and buzzer. I learned how sensors and Arduino outputs work together.

### PIR Motion Detector This project uses an **Arduino UNO, PIR motion sensor, and LED** to detect movement. The PIR sensor detects motion and sends a signal to the Arduino. When motion is detected, the Arduino turns the LED ON, and when there is no motion, the LED remains OFF. When it detects movement, The Yellow led turns on for 4 seconds.

I made a car parking system. We cannot know what is before our car if we are parking it backwards. This project is about it. When something comes too close it detects it and the buzzer rings fast. I learned how to make it and I also learned about buzzers and ultrasonic sensor. This type of tecnology is used in modern cars

I made a parking assistant using an Arduino UNO and an ultrasonic sensor. It checks how close an object is to the sensor. When the object comes within 10 cm, the LED turns on to give a warning. I tested it by moving my hand closer and farther from the sensor.

I made a distance measuring project using an Arduino UNO and an ultrasonic sensor. The sensor sends sound waves and receives them back when they hit an object(Mohitbhai had taught this before when I was in 6th standard). The Arduino then calculates the distance and shows it in centimeters on the Serial Monitor. I tested it by moving my hand closer and farther from the sensor.

I made an automatic night lamp using an Arduino, an LDR sensor and an LED. The LDR checks if the place is dark or bright. When it gets dark, the LED turns on, and when it gets light, the LED turns off. I also used the Serial Monitor to check what the sensor was detecting.

made an automatic night lamp using an Arduino, an LDR sensor and an LED. The LDR detects if the surroundings are bright or dark. When it gets dark, the LED turns on, and when there is enough light, the LED turns off. I learned how an LDR sensor can be used to control an LED automatically.

made a light sensor using an Arduino UNO and an LDR sensor. It can detect if there is light or darkness and shows the result on the Serial Monitor. I learned how to connect the sensor to Arduino and how the sensor detects light. I tested it by covering the sensor and shining light on it.

I made a 5-LED pattern selector using Arduino and a push button. Each press changes the LED pattern. I learned about LEDs, buttons, Arduino coding, and functions.

I have made a RGB led change the brightness of each of its colors. The colors of it are red, green and blue.

So we all know that we can change the pattern of how led s glow using an Arduino and its code. But in that, we cannot just change it in the middle(pattern). But in this project, I changed how the LEDs would glow using a potentiometer. It was a really cool project. I learned to use a potentiometer to change how LEDs glow.

So this project was different. In previous projects, it was all about the physical components. But in this project, I had to read the potentiometer values. Basically, the potentiometer has values and the value changes if we turn the knob. So the serial monitor helps us read the values. Overall, it was a really fun project to do.

I MAKE A LED CHANGE IT BLINKING SPEED

So this is a very interesting project I made. We all know we can turn an LED on and off. But in this project, I made a project that can control the brightness of an LED. It was easy and fun to make. This project required a component known as a potentiometer. It is the part that helps lower or increase the brightness of the LED.

I made a buzzer turn on for 3 seconds if pressed the button. it was my first buzzer project

I made a led toggle. it was fun and similar to the previous one but this one stayed on when i pressed once and turned off after pressing it one more time

I made a led on when i press button and of when not press button

I made a led turn on in 5v by Arduino. First, my green LED was glowing yellow, meaning it was heating up, but i figured it out that how can i make that light green.

I made 4 leds blink one by one in speed. It was like diwali lights but on a breadboard. My photos of documentation might look same as i have 2 red lights that are next to each other.

I built leds blink in a specific pattern.

I made a led blink in a change pattern, also when it reaches the end it chases backwards.

I built an led turn on one by one. It was cool.

I made leds glow in a specific pattern. I knew when it was complete when all of my leds glowed in that specific pattern

I made 4 leds blink using a arduino and breadboard. it was easierto do then the previous one as it only had 4 leds

I made 8 leds tur non and off after each other. The hard part a bout it was to insert everything as i had to put the anode, resistor and the wire that would help it to connect to arduino in in 5 studs.

I built chasing led. it was like one more color added to the trafficlight

I made 3 leds chase. it is like a traffic light

I built a chasing led. It looked like they were playing passing the parcel but the parcel was electricity

I build a led blink in a specific pattern.

So in this project, I made a custom pattern of blinking. It was very fun to do. It was comparatively harder to do than the previous one, but it was worth it. I knew when y project was complete when it started to blink in a pattern that I wanted it to blink.

I built an led blink on and of in 1 second instead of 2. It was hard to take photo for documentation, but i managed to click one where it is blinking.

I made a LED wait and lit for 2 secons. it was easier to take pictures for documentation.

I made 8 LEDs blink. I made it through my creativity

i made 5 leds blink and 1 was in the center. i also used my creativity and i did not copy.

I built 4 LEDs blink at the same time. I have also used an red - green led. that led changes its color to green and red in 1 second.

I built a blinking led and I learned how to blink an led using a breadboard. I knew when the challenge was complete when 2 leds blinked on and off.
