µBoost is a Single AA powered, 3.3v 100mA power source and flashlight and it can run low power devices. µBoost is small, portable, 3.3v 100mA power source for low power devices like Arduino Mini. It has white power LED and can usable as flashlight. Also it has "Battery OK" indicator...

8 Digit serial numerical display shield for Arduino has been designed for various applications like digital clock, stop watch, score display, temperature meter, frequency counter, digital meters etc. The circuit uses popular MAX7219 IC and two common cathode 0.5inch red seven segment...

Arduino Nano Bar-Graph display with universal op-amp shield consists of 10 LEDs and single low voltage general purpose LMV321 op amp including few capacitors and resistors connected to op-amp pins. The op-amp proto area can be configured without any modifications to the board and all...

1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET...

Chromatron is an open source Wifi pixel controller designed to make LED pixel projects easy and fun. Hi, I'm Jeremy! I've designed a toolkit for making art with LED pixel strips, and I'd like to share it with you! Chromatron takes custom designed hardware and feature-packed firmware,...

Martina @ natural-nerd.com build a sound reacting LED light using Arduino: Hi! In this build we’ll make a good looking light that dances to all sounds and music, using simple components and some basic Arduino programming. It makes an awesome effect while standing on the desk when...

LucaBellan @ open-electronics.org  re-created the Ambilight TV effect on any other TV using Raspberry and Kodi. He writes: The screen’s edges are divided into logic sectors, and each sector is associated with a specific LED and, by making a color average of the pixels, you can find...

Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy.  It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and...
