The Arduino Extension is a newly added feature to the OpenPLC editor. It allows Arduino Sketches to be added to and run alongside a PLC program. It supports almost every Arduino library and code that ...

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 ...

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… ...

For this, just wire up the hardware (arduino+keypad) as described earlier. Although the code is an entry-level one, it includes a secret key option that will need to be entered on the keypad.

In this Arduino motor control tutorial, we’ll guide you through interfacing the L298N with Arduino, understanding its working principle, and writing code to run a DC motor forward and backward with ...

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

This example code wakes the onboard indicator (LED at D13) of the Arduino when a tilt is inputted by the tilt sensor module through the occupied digital input (D2).

If you’d like to skip needing to use a second Arduino, we’ve seen some other tools available for debugging Arduino code that can run straight from a connected PC instead.

Arduino Core for ESP32 has received a wrapper library that makes it easier to use ESP32-H2 and ESP32-C6's Zigbee radio in Arduino projects.
