An RGB LED module is a versatile lighting component that can produce millions of colours by mixing red, green, and blue light. The RGB LED module used in this ESP32-S3 Box-3 Arduino programming ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

This repository contains various Arduino projects implemented in C and C++ to explore embedded programming concepts. The goal is to understand low-level hardware interaction, memory management, and ...

A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches connect a row to a column when ...

Making time for my next small Arduino project, I need to do something with the rotary encoder direction information decoded by this software. A state machine is what I need, but how to implement it?

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Arduino has announced the new UNO R4 board family, a new platform for enthusiasts, hobbyists, students, and professionals to create prototypes, innovative solutions, and other interactive electronic ...
