This tutorial will guide you through the basics of controlling an Arduino at a low level using port registers and bit manipulation. We'll end with a practical example of blinking an LED using direct ...

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 is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

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 ...
