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 ...

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 ...

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 ...

This library runs TensorFlow machine learning models on microcontrollers, allowing you to build AI/ML applications powered by deep learning and neural networks. With the included examples, you can ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

A few years ago, building a drone was expensive and out of reach for most hobbyists and students. But today, DIY drones… How to Build an IoT-based Weather Monitoring System Using Arduino? Have you ...

This example demonstrates the use of pinMode(INPUT_PULLUP). It reads a digital input on pin 2 and prints the results to the serial monitor. /* Input Pull-up Serial This example demonstrates the use of ...
