Introduction to Arduino Nano The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P. It has more or less the same functionality as the Arduino Uno but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. Available … Read more
Materials Instructions Connect the DC motor to the L298N motor driver module. Wire the motor driver to the Arduino and the external power supply as per the module’s pinout. Upload the following code to your Arduino: Explanation This code alternates the direction of the DC motor by switching the state of the pins connected to … Read more
Introduction This project focuses on creating a simple water level indicator using the Arduino Uno. The water level indicator will use basic components to monitor the water levels in a container and signal when the water level reaches a certain point. This project is useful for applications such as water tanks and reservoirs where monitoring … Read more
Introduction In this project, we will create a simple motion detector using the Arduino Uno. This motion detector will use a Passive Infrared (PIR) sensor to detect motion and activate a buzzer when motion is detected. This project is ideal for beginners and provides a practical application of Arduino and sensor interfacing. The PIR sensor … Read more
