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…

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…

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…

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…

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:…

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…

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…

To make 3 LEDs blink like traffic lights (Red, Yellow, Green), you’ll need to follow a simple sequence of turning each LED on and off in a timed pattern. Below is an example of how to implement this using a…

Connecting more than one LED to the same pin on an Arduino can lead to several potential issues, depending on how you wire the LEDs. Here are the main things that could happen: 1. Parallel Connection (Incorrect or Risky Setup)…
