To create a simple light-sensitive alarm system using a Light Dependent Resistor (LDR) and a buzzer, you can follow these steps using an Arduino microcontroller, LDR, and a buzzer. Here’s how to build the system: Components Needed: Circuit Diagram: Code…

The SmartTime Watch is an Arduino-based smartwatch that displays the current date and time on an OLED screen when you bring your hand near an IR sensor. Using a Real-Time Clock (RTC) module, the watch accurately shows the date and…

This project will allow you to control a small DC motor (representing the fan) based on motion detected by a PIR sensor. When the sensor detects motion, the motor will turn on, and when no motion is detected, the motor…

Here’s how you can build a water level monitoring system using an Arduino and a water level sensor, with the water percentage displayed on an I2C LCD. Components Required: 1. Wiring the Components: Water Level Sensor: I2C LCD: 2. Arduino…

This project involves creating a simple snake game using an Arduino, a joystick for controlling the snake, and an OLED display to show the game graphics. The game will use basic components, including a joystick module to control the snake’s…

In this tutorial, we’ll show you how to build a simple stopwatch using Arduino. This project will involve setting up a button to start and stop the timer, while displaying the elapsed time on an LCD screen. It’s a great…

To make a smart dustbin using Arduino, an HC-SR04 ultrasonic sensor, and a servo motor, the project will automatically open the lid of the dustbin when an object is detected nearby and close it when the object is removed. Here…

To build an IoT project using Arduino to measure ambient light levels and display the result on an I2C LCD screen in percentage, you can follow these steps: Components Required: Wiring: Arduino Code: Here’s the step-by-step code to read the…

Here’s the Arduino code that will turn on an LED when you put your finger on the LDR (Light Dependent Resistor). When the light falling on the LDR decreases (due to the shadow of your finger), the resistance increases, and…
