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 ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...

The annual Consumer Electronics Show is in session, which means thousands of people have descended on Las Vegas to stare at next year's dust-gathering trash. Maybe you can do better. Maybe it's time ...

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 ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty to look ...

Arduino has recently introduced a new Bluetooth-based provisioning flow on the Arduino Cloud, starting with the UNO R4 WiFi ...

I’m not a fan of educational toys. They’re usually either too educational or too toy-like and, in the end, kids get little education and little fun. The Code Kit from LittleBits has changed my mind.
