LED Sun rise/set Arduino Proj

I've been slowly working on this project for the past month or so. I finally have some time to share and post-up what I'm working on. I know there are commercial products available, but then what's the fun in that! What I want is a Fully Automated LED Primary Lighting System which can control separate white and blue high-powered LED modules on my 45gal bow-front tank. What I mean by fully automatic is that ...

Nerd++: Controlling Dioder RGB LED Strips with Arduino, Pt. 1 – Getting Started

A few weeks ago, it came to my attention that IKEA do a set of colour-changeable LED strips. I’ve been looking for a decent way of providing some lighting behind my computer to reduce eye-strain for a long time, and these seemed perfect: I was very pleased with them, but no self-respecting nerd would stop here. Especially one who’s seen Philips’ Ambilight technology in action! Over a series of blog posts, I ...

Arduino LEDs

Description In this tutorial you will set up and turn on a single LED. Note that this code can actually be executed with just the Arduino and no other components as in Figure 5. If you notice, next to pin 13 is a tiny LED on the board. If you execute the code below, you should see that LED turn on. Note: In the photos/video you will see me use a 1.2k&#8486 resistor. I did this to back off the brightness ...

Arduino Tri-colour LED Flasher Circuit

This simple tri-colour LED flasher circuit is great for beginners. The three pin tri-colour LED is controller by an Arduino Uno and changed between three colours. This video shows the Arduino running a sketch that controls the tri-colour LED. Circuit Diagram for the Arduino Tri-colour LED Controller The circuit is very simple, using only three components. The tri-colour LED is a three pin common cathode typ ...

Blink

This example shows the simplest thing you can do with an Arduino to see physical output: it blinks an LED. Hardware Required Arduino Board LED Resistor, anything between 220 ohm to 1K ohm Circuit To build the circuit, connect one end of the resistor to Arduino pin 13. Connect the long leg of the LED (the positive leg, called the anode) to the other end of the resistor. Connect the short leg of the LED (the ...

Tutorial 4: Arduino Knight Rider

In this tutorial, eight LEDs are interfaced to the Arduino Uno board. This is not complicated – it is just like interfacing a single LED to the Arduino as done in tutorial 3, but eight times over. A program is then loaded to the Arduino that will turn the eight LEDs into a "Knight rider" display. The following video shows what you will achieve: Prerequisites You will need to have completed tutorial 3 and it ...
