Arduino Nano: Simple LED Blink Program

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

Arduino Project: Auto On/Off LED with RTC and LCD Display

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

How to display the time on an LCD using a real-time clock (RTC) module?

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

Displaying Temperature on LCD Screen Using Arduino with DHT11 Sensor

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

How to Display Button Press Status on an LCD using Arduino?

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

How to make a message, like “Hello”, scroll across the LCD?

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:

How can you make a buzzer play a melody with your Arduino?

To make a buzzer play a melody with an Arduino, you can use the tone() function to generate specific frequencies that correspond to musical notes. A simple way to do this is by using an array of note frequencies and durations, then iterating through them to play the melody. Wire Connection: Arduino Code: Explanation: This … Read more

How can you make an LED slowly get brighter and then dimmer again?

To make an LED slowly get brighter and then dimmer again, you’ll need to control the LED’s brightness using Pulse Width Modulation (PWM), which is supported by several Arduino pins. You can achieve this by gradually changing the duty cycle of the PWM signal. Components Needed: Circuit Setup: This limits the current flowing through the … Read more
