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… ...

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

How it works: When something triggers the sensor, the Arduino records that moment as triggerTime in Line 23, and compares it with the current time based on conditions in lines 26, 29, and 34.

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It's completely open source and the notifications system runs on your ...

[Gesyuk] is using an Arduino clone by the name of Funduino Mini Pro, a 2-channel, 2-way relay, — he only needed one, but you use what you have on hand — a recycled power supply to convert 220V ...

The components required to create the system include an Arduino Nano development board, digital potentiometer, flex sensor, a pair of push buttons an IMU, and of course a glove.
