In this instructable i will explain how to connect 7 segment display, decoder and arduino. It´s pretty easy. At first we have to learn something about decoder. I´m using BCD to 7 segment decoder. My is D147D, this is old chip, but the newer are similar. Documentation about one of them you can find here

I used the Arduino UNO combined with three LumiGeek shields to run lighting. LumiGeek has dedicated shields to support 1 Watt RGB LEDs that require constant current, Addressable RGB LED Strip, and Non-Addressable RGB LED Strip. Step 1: 1 Watt RGB LEDs (2x) I wired these in series and powered them with the 12 Volt

Greetings! I’m Russell Petersen. I’m an engineer, inventor, designer, fabricator, and dreamer. I’m a junior Electrical Engineer by trade, located and working in the San Francisco Bay Area. I love playing with Solid State Lighting, and came up with this idea one night. Simply stated, It’s a custom built light box with a logo adhered

RC MOOD LYTE is a commercial quality flameless light engine for heavy, everyday use in the home, restaurant, catering and hospitality industry ,a great improvement over the traditional wax candles in terms of safety and reliability features . LED Candles have No wax, No smoke, No heat, No mess. ECO BENEFITS Safety: eliminates fire danger
This instructable primarily shows how to control the charging voltage from a solar panel to an energy storage device (capacitors in this case). I showed how to construct the light previously http://www.instructables.com/id/Human-Powered-Light-from-my-book-Doable-Renewab/ Step 1: This solar panel can produce up to 18 volts, but my capacitor bank should never receive more than 15 volts. I

In this instructable the main focus lies on the software which I’ve created – not so much on the hardware side. You needn’t to use a high- power led for this, you can use every RGB- LED you like. The “High Power RGB LED Moodlamp” is a high power rgb led lamp which can be

This example shows you how to read different analog sensors to change the brightness of the three colors in the RGB LED. In this example you will read the amplitude from the microphone, the amount of light on the light sensor, and the position of the linear potentiometer. These three sensors will control the intensity

Build an Arduino-powered version of the “Four Letter Word Generator” (FLW). This version generates “words” on the fly – it does not use a list. The “original” version from the 1970’s used B7971 nixie alphanumeric tubes. These tubes are getting hard to find and they’re certainly expensive. They also require interfacing with high voltage and

Let’s be honest for a moment, doesn’t everyone want a dress that lights up at your very whim? No? Alright, well I do. It’s pretty straightforward, though the programming gets a wee bit tricky. So pick up your pencil, sketch out a design and then we’ll talk parts.Here Step 1: Material Step 2: Schematics Before jumping

This display is based on an 8×8 RGB LED Matrix. For testing purposes it was connected to a standard Arduino board (Diecimila) using 4 shift registers. After getting it to work I permatized it on a fabbed PCB. The shift registers are 8-bit wide and are easily interfaced with the SPI protocol. Pulse width modulation
