Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an HO layout on a 4 x 8 sheet of plywood in my parents' basement in Reading, ...

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape. By The Big Book Of Hacks Published Jan 10, 2013 3:00 AM EST Get the ...

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

With these mods, this circuit will last quite a long time, especially if you make things easier for the relay by turning off power to the motor before switching directions. It is simple and effective ...

Sure, you can buy a cable tester, but what fun is that? [Ashish] posted a nice looking cable tester that you can build with or without an onboard Arduino. If you don’t use an Arduino, the project uses ...

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output in all sorts of ...

The latest Arduino board called Primo integrates Bluetooth low energy, NFC Touch-to-Pair, Wi-Fi, and an infrared interface, all without having to add extra shields to the base board. The Arduino Primo ...

An Arduino Uno-compatible home automation board requires no separate power supply as a power source soldered onto the board itself. According to the developer GarageLab, it is supplied directly from ...
