The purpose of this small scale LED marquee is to display messages to our classroom in a more modern and centralized way. In the classroom, this construction would save white board space and is convenient because it can store a large amount of information. It is also fairly simple to program and has a mount, […]
I am going to show you how you can use an RGB LED and a Cds photocell as a colour sensor for a micro-controller. I will illustrate the method to retrieve a colour using Arduino, and I will show you a how you can verify the colour being scanned with a small Processing sketch.We will be

Last year my Wife and I started a new tradition of building a Gingerbread house for Christmas. We had a few nicely decorated houses last year, and I wanted to do a little more this year. Adding LEDs makes everything better, so that is exactly what I did! This instructable will show you how to
This is an instructable for the Interactive LED Lab Coats, showcased at Autodesk University. Check out the videos below! The first is a demo of the colors actuated by the buttons. The second is a demo of the breathalyzer! (this will be explained later) Tools Sewing machine Soldering iron Wire cutters & strippers Hobby knife
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

It’s to make a fist pumping LED controller. What is it? Have you noticed yourself fist pumping to the music at a party or a club? That’s exactly for that. You would wear a band with a accelerometer/gyro mounted. As you move your hand around the air, the movement will trigger a light board and

Time for something a little more advanced. Direct Port Manipulation. Normally when using Arduino software, the actual logic behind changing the values in pins is abstracted away with digitalRead and digitalWrite. Now, for most people that’s just fine. But it has some limitations. For one, it is a little slower than might be practical for

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
Addressable Milk Bottles (LED Lighting + Arduino) using arduino Continue Reading
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
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
