High-power LEDs over 1W are now quite inexpensive. I’m sure many of you are incorporating LEDs as light sources in your projects. However I realize that the finding and configuring the power supply is still not as simple as it can be; commercially available LED drivers are convenient, but often overkill or not flexible. Even …

This a Knight Rider Style LED Chaser Done with a Arduino Duemilanove with an ATmega328 chip. Step 1: Things you’l need: 6 LEDs (any color) 1 Breadboard 1 100 Ohm Resistor 12 Breadboard Jumpers 1 Arduino Duemilanove “or” Decimila 1 USB cable with A-type connector on one end, and B-type on the other. (See photos) …
This is my second instructable. i want to share some of the basic things i made using the arduino i am so busy lately. then i got the chance to have this spare time… inspired by my former student and a fellow co league to share this arduino based wireless automation. this automation was done …
SOS is the commonly used description for the international Morse code distress signal (· · · — — — · · ·). [read more on wiki] Requirements: 1) Arduino 2*) 8 Ω speaker 3*) 150 Ω or similar resistor 4) 5mm RED LED 5) Hook-up wires 6) Any breadboard * Ω = Ohms Step 1: …

So you’re here because you want to start learning some of the Arduino Basics… So let’s start with THE most basics… no this “tutorial” is actually a little more basic than what you have in mind. It only requires that you: Have ANY Arduino Board. Have installed the drivers and required software for the board …

For a recent project I needed to build a large and obvious bar graph display. This was to show the power generated from a bicycle generator. I came up with this design and was pretty pleased with the final results as it is relatively low cost but still pretty visual. It stands 1.5m high and …
This instructable will show you how to create a dice using Arduino and few components. It’s an easy and fun project, suitable for beginners and those who want to start with Arduino; it also requires a minimal amount of components. This explains how to create it in the breadboard, how to solder it and how …
I’m still working on the LED calculator (original idea and most recent work) — I’ve finally got ’round to adding a rotary encoder to set the target system voltage. Now you can turn the potentiometer to set the LED brightness, turn the rotary encoder to set what voltage will be used in the ultimate LED circuit, and …
As someone who is very new to digital electronics this LED cube was fun to make, challenging and a great lesson in soldering. If you have some patience (64 LED’s to solder!) and steady hands, this project will be well worth it in the end! Step 1: Materials & Tools Materials: -64 LED’s ( I …
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 …
