HOW-TO: Music Reactive Desk Light

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 gaming, playing music, and anything else that makes sound really. Let’s get going! (Click here to download schematic) STEP 1: MAIN SUPPLIES First things first: what kind of supplies do we need and what do ...

RGB LED Cube with Sound to Light Capabilities

The objective of our final project was to build a 5x5x5 RGB LED cube that can display a certain color depending on the frequency of music playing. There are two main components of this project. [gallery columns="2" size="medium" ids="31240,31241"] The first part is the hardware setup that consists of the LED cube and the circuits that drive the power for each LED which is controlled through an Arduino Uno m ...

RGB LED Strip Clock

For the final project we made an analog style clock with an Arduino microcontroller. To do this we used three major components: an RGB LED Strip, a DeadOn RTC, and a custom user interface. The LED strip is used to set the display around the clock. The DeadOn RTC is used to keep time independent of the microcontroller and communicates using SPI. The custom user interface allows the user to make various selec ...

RGB LED Grid

This project involved creating a red, blue, green (RGB) light emitting diode (LED) matrix that displayed the colors of the rainbow. The colors of the rainbow were chosen to show the full color spectrum that the LEDs are capable of, while still giving distinct variation within the LED matrix. [gallery size="medium" ids="31125,31124,31123"] In this project, each diagonal of the LED grid is a different color o ...

Plant Moisture Monitoring and Watering with LED Indicator

Monitor your plants and let them water themselves when they are thirsty. Story Motivation I work in a rather 'sterile' office, that was once a server room with raised floors. After several years working in there, I got tired of no windows, no outside light, and NO GREEN things, and decided to bring in one of my many plants, from home, in an attempt to bring a little 'green' inside. I brought the plant in an ...

3D-Printed RGB Wallet

Stand out from the crowd with this unabashedly ostentatious excuse for a wallet. It's got plenty of space, RGB lights, and you can even put your name on it for added vanity. Interested? Keep reading! In the files section of this build you can find two things: a Fusion archive and some STL files. If you're just interested in printing a blank wallet without any text on it then download the STL files. Load the ...

Controlling RGB LED using Arduino and Wi-Fi

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we have used an Android Mobile App named “Blynk”. Blynk is a very compatible app with Arduino, ...

RGB LED with Arduino

In this project we are going to interface 5 RGB (Red Green Blue) LEDs to Arduino Uno. These LEDs are connected in parallel for reducing PIN usage of Uno.  The RGB LED will have four pins as shown in figure. PIN1: Color 1 negative terminal or color 1 positive terminal PIN2: Common positive for all three colors or common negative for all three colors PIN3: Color 2 negative terminal or color 2 positive termina ...

Volcom RGB Desktop Light Box

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 to the front, and lit by a RGB LED module. This project is easily adaptable ...

1 LED Game with Arduino Uno and an RGB LED

Sometimes I just have those days where I really want to make something neat with the Arduino I have lying around, but I know I don't have the patience for a more involved project that'll take more than a day or so. This is for one of those days. The premise is as follows: A random color is shown on an RGB LED for a few seconds, then extinguished. You, the player, then press and hold a button to cycle throug ...

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 ...

RGB LED Disco Lights

RGB LED disco light is a simple project designed around PIC16F72 microcontroller. This firmware is a RGB driver, as name suggests it is used to derive or light red, green and blue LEDs in particular fashion. Its main feature is the pattern shown on LEDs. It is quite difficult to describe pattern in words but we want to specify that first it will derive red then green then blue three times and then a particu ...
