In this tutorial, you will learn how to interface a DC motor with Arduino using a motor driver IC (L293D). DC motors are widely used in embedded systems for motion control applications such as robots, conveyor belts, automatic doors, and small automation projects. Many beginners try to connect a DC motor directly to the GPIO

In the previous blog post, we learned how to control a relay using a push button and an Arduino. Now, let’s build another practical Arduino project using a push button and a piezo buzzer. In this tutorial, we will program the Arduino to buzz when a button is pressed. You will also learn how to

In the previous post, we learned how to control an LED using a push button and an Arduino. Now, let’s take the next step by building a simple yet practical Arduino project that uses a push button to control a relay. Relays allow low-voltage microcontrollers like Arduino to safely control high-voltage or high-current devices such

In the previous post, we learned how to blink an LED using an Arduino. Now, we are taking the next step by building a simple and interactive Arduino project. In this project, we will control an LED using a push button. It helps you understand how to work with digital inputs (push buttons) and digital

In this “Arduino traffic light project”, you will design and implement a working traffic light system using LEDs and Arduino code. In this project, you will learn how Arduino digital pins operate, how to control output devices, and how to write a non-blocking code, and how to write timing logic that mimics real-world traffic signal

“If you have ever tried to blink multiple LEDs at different speeds using Arduino and wondered why your board behaves strangely, then believe me this blog post is for you.” Blinking multiple LEDs at different speeds using Arduino board is a very common requirement once you move beyond a basic project. When I was learning
