I frequent a blog called hackaday.com which featured a project by “Nikolai”, it was a 10cm LED ball that used shift registers. It seems like a really fun project to attempt but the cost of having the boards made & not having any experience sending eagle drawings to fab shops initially kept me from starting. …
There are a number of great Instructables on LED grids out there. This is a low cost version – not quite as polished, but easy to make. This project uses a couple of sheets of foam core, a fluorescent fixture cover from the local home store, a cut up strip of WS2812b LEDs, and an …
Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you …
These two integrated circuits from Maxim are for driving either 64 individual Led’s, or up to 8 digits of 7-segment displays. The drivers implement a SPI compatible slave interface that can be controlled from the Arduino using only 3 of the digital output pins. An extensive datasheet for the IC’s is available from the Maxim homepage. Since both …

In this inst’able, I will show you how to create your very own 4×6 LED matrix as well as show you how to write code for it! There is an animation creator program in step 4! Here is one ANIMATION to get you excited about the project! ***Wave Animation*** Hello everyone! I’m back with an all new Inst’able! …
Custom made Multiple color display. Have you ever wanted a display that is a little larger then one you can buy? Have you ever wanted to make a display the way you wanted it? Me too! This is how I made a custom multiple color display that I use for temperature. Step 1: Supplies and …
Project-specific parts You’ll need the standard parts (Arduino board breadboard wires pliers and so on) along with these extras: DHT11 temperature/humidity sensor 7 x 330-ohm/0.5W metal film resistors 3 x 4.7k-ohm/0.5W metal film resistors 2 x BC337 NPN transistors 2 x LTS543R or FND500 common cathode seven-segment displays They shouldn’t cost you more than $15 …

give your Arduino a 120 volt kick in the pants! The Arduino is a great tool for anyone interested in learning microcontroller programming, but after blinking some LEDs, what’s next? This project enables your Arduino to control real-world 120 Volt electrical appliances you have in your home. what can you use a plugduino for? Well, …

In this project we’ll create a small add-on PCB containing the a MSGEQ7 spectrum analyzer circuit and show how it can drive the RGB LED cube kit from Freetronics. This allows the cube to display the seven bands over four horizontal planes. There is a small amount of assumed knowledge for this project – To save repeating …
Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by. Among other things, I wanted to …
