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 ambient light level, convert it to a percentage, and display it on the I2C LCD. … Read more
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 the Arduino will detect a lower light level. The LED will then turn on. Wiring … Read more
To build a Simple Light Meter that uses a Light Dependent Resistor (LDR) to measure ambient light levels and display the result on an I2C LCD screen in percentage, along with an LED to indicate light levels, follow this guide. The project will read the LDR values, calculate the light intensity percentage, and display it … Read more
To get started with Arduino Nano, the first code you’ll often write is the “Blink” example. This program makes the built-in LED and External LED blink ON and OFF. The Arduino Nano, like other Arduino boards, has a built-in LED connected to pin 13. If you want to use an external LED: If you want … Read more
This project demonstrates how to use a real-time clock module to trigger actions at specific times and display the current time on an LCD screen, providing a basic automation system. We will create a simple system that automatically turns on an LED at 5:00 PM and off at 5:10 PM. The system will also display … Read more
This project demonstrates how to use an Arduino to display the current time on an LCD screen. We’ll use the DS3231 RTC (Real-Time Clock) module, which keeps accurate time even when the Arduino is powered off. The time is displayed on a 16×2 I2C LCD display, which is easy to interface with the Arduino. Components … Read more
In this project, we will guide you through the process of showing the temperature on an LCD screen using an Arduino board, a DHT11 temperature and humidity sensor, and an I2C LCD module. The DHT11 sensor is a simple, low-cost sensor that can measure temperature and humidity, while the I2C module makes it easier to … Read more
If you’re looking to learn how to use an Arduino to increase a number every time you press a button, this project is a perfect way to dive into both basic electronics and programming. In this tutorial, we’ll show you step-by-step how to set up a simple circuit with a button and an LCD screen. … Read more
In this tutorial, we’ll learn how to show the status of a button (pressed or not pressed) on an LCD screen connected to an Arduino board. The LCD will use an I2C (Inter-Integrated Circuit) interface, which simplifies the wiring and programming. We will write a small program that updates the LCD to display whether the … Read more
To make a message like “Hello” scroll across an LCD using an I2C module with a 16×2 LCD on an Arduino, you need to follow these steps. Below is the Arduino code and the circuit setup. Circuit Setup: Arduino Code: Explanation of the Code: Final Notes:
