This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

This project demonstrates how to build an RFID-based access control system using Arduino. The system integrates an RFID reader, servo motor, 16x2 LCD (I2C), three LEDs (Red, Yellow, Green), and a ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

(keypad: columns and rows switching) So now you can see how the button presses can be translated into electrical data for use with a microcontroller. We can now start the real experiment with as ...

Using an Arduino and a little code on your PC, it monitors your screen and creates lighting behind your monitor.

Having easily parsed code reduces your cognitive load and makes solving problems easier. To try and help with this, [PTS93] developed the Stator library to make certain common tasks simpler to read.

Embedr is an AI-powered Arduino-like IDE designed to simplify development for Arduino-compatible microcontrollers. It looks very similar to the Cursor code editor and uses Microsoft’s Monaco Editor ...
