Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

This project demonstrates full-duplex SPI communication between an ESP32-S3 (running Zephyr RTOS) and an Arduino Uno. The goal is to send one full string from the master (ESP32-S3) and receive one ...

This week I will outline a project for Halloween that uses the Arduino and a light to create a glowing effect inside a pumpkin. I use artificial pumpkins for projects like this so I can reuse them in ...

Light painting is a technique which allows you to “draw” on a photograph by moving a light past the camera during a long exposure shot. While it can be difficult to master, light painting allows for ...

setup() Function: This function runs once when the Arduino is powered on or reset. It sets pin 13 as an output (where the LED is connected) and initializes serial communication at a baud rate of 9600.

Today, we are building a simple Arduino-based project: a light-following robot. This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver ...

Arduino is a well-known open-source electronics platform that provides users with the ability to create interactive and easy-to-control systems in a reliable manner. A popular use for Arduino boards ...

A light meter is a very useful device that finds applications in hospitals, schools, factories, parking lots, passageways, and many more to measure and maintain adequate lighting levels. It is also ...
