This is a little art project I made with 95 RGB LEDs arranged in a 3D cylinder shape, sitting atop a microcontroller-based driver circuit. The LEDs are individually addressable, and when you power it on, the software cycles through a series of animations, e.g. various moving rainbowy patterns, “rain”, “fireworks”, and so on. It doesn’t […]
Ah yes, it’s time for another Instructable involving an Altoids tin… But this time it’s not about what’s inside the Altoids tin, it’s about the Altoids tin itself. In all its greatness, the Altoids tin we all know and love has one rather major flaw for DIY electronics use: it’s electrically conductive. To combat this, […]
How To Interface a CDV 700 Geiger Counter to a PC Using an Arduino (Part 1) The second part of our video series of our project to interface to a CDV-700 radiation meter using an Arduino Uno! How To Interface a CDV 700 Geiger Counter to a PC Using an Arduino (Part 2) Code: A […]
So I had some luck with getting the Sharp Infrared range finder working and I’ve now plugged this on to my servo rig to see if I get better results on my radar styled display. Check out how to use the Sharp IR range finder here Few things to bare in mind, whilst the code […]
As a beginner myself, I struggled to find a one-stop set of instructions to get up and running with Sparkfun’s Motor Driver 1A Dual TB6612FNG. This motor driver breakout board is exceptional value, is beautifully small, but does need a little more effort to get it working. The TB6612FNG is an H-Bridge driver – I […]
This instructable is not complete, I will post code soon The Arm: This instructable shows the process of building a robotic arm using servos, Arduino microprocessor, a gyroscope and multiple bend sensors. The user wears a glove containing the gyroscope and bend sensors which translate the movement of the users hand into motion of the […]
I made this project on the same night that my Arduino Duemilanove arrived from Cool Components. After being an Instructables member for about a year I though it was time I should contribute. There is another Arduino traffic light project similar to this, but it is much more complex; mine is aimed at beginners and […]
Using an Apple Pro speaker, I made a flashing RGB LED iPod dock for about $35. I recommend reading the entire ‘ible before starting. Also, note that the volume is control from the iPod. It consumes minimal power in shutdown mode, and is controlled by a Teensy. This took me ~3 days to build, and […]
This is where all the work is done to read an interpret the values from the servo and the sensor. If the readings are to erratic then you won’t have nice shapes. Also if you don’t allow enough time to the signals to be sent back then you’ll get false distance readings. So this code […]
So far my Arduino projects have all needed only a small number of output pins. In a previous post I talked about moving some of the logic off the Arduino and into other integrated circuits in order to free up pins on the Arduino. While this can help, I’m sure there will come a time […]
