This instructable will guide you through the process of making your very own star-cluster from LEDs and acrylic. I made this piece for my electronics final project at college and had access to a machine shop. This instructable assumes that you have access to similar tools. This project was very much inspired by http://www.instructables.com/id/working-progress-n-how-to-make-a-multilayered-a/#step8. Step 1: […]
As an artist, sometime I created an art pieces without planning ahead what I want to draw or paint, just want to add colors or lines onto the drawing or canvas, and never think of the outcome of the piece. Let’s our own instinct and subconscious leading away! Then I thought, “What if I am using electronic components, […]
The String case change functions allow you to change the case of a String. They work just as their names imply. toUpperCase() changes the whole string to upper case characters, and toLowerCase() changes the whole String to lower case characters. Only the characters A to Z or a to z are affected. Circuit There is […]
This is my first time using Arduino, or any microcontroller. I’m glad it worked out so well but my wife may not be, due to the stacks of microcontrollers that will being showing up on our doorstep soon for future projects. Any feedback or questions are welcome, as are votes in the Arduino Contest. Why (Problem) […]
Remote visualization of real-time sensor data. This tutorial describes in detail how to use the free SensorMonkey service to push real-time sensor data from an Arduino to a webpage for visualization using Processing.js. No server-side coding or Ethernet shield is required. A standard, run of the mill Arduino will work perfectly. You’ll also need a sensor to […]
ArduSniffer This Instructable shows how to build a gas detector / indicator using an arduino. The finished product is USB powered and displays the amount of detected gas on a led display. In this design the reset button on the arduino is also working. This project will cost you between €25,- and €65,- depending on […]
You can add Strings together in a variety of ways. This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an […]
This Arduino project will display RSS feed headlines on an LCD via an Arduino and a USB cable. It works quite well, and lets you keep up with the world news while you’re sitting at your desk. Many of the values in the code can be changed, and the system can be adapted to display […]
Here’s a six word tragedy: My arduino needs four AA batteries. Really? Isn’t this 2012? Where’s my jetpack?!! Here’s a way to the future — a way to make a solar panel, from scratch, that can power any arduino off of sunlight or even light in your house. Sort of a peel-and-stick power source for […]
LED displays are commonly packaged as arrays of LEDs organized in rows with shared positive terminals and columns with shared negative terminals, or vice versa. Here is a standard illustration, along with its diagram: These exhibits can be very useful. To control a matrix, you connect its rows and columns to your microcontroller. The columns […]
