Using an Arduino Uno R3 as a Game Controller

Naturally, the Uno does not natively support keyboard strokes, unlike it's Leonardo brother. Most of Google will tell you you need to do some firmware workarounds and ATMEGA reprogramming just to get it working and the entire ordeal is a mess. If you're like me, you've found that out just after buying one. Here is how to get around all that using a bit of Java coding. The ideal solution would be to purchase ...

Arduino Sew Easy Wearable Shield

Wearable computing, e-textiles, soft circuits or whatever you want to call it, is a growing field of applying technology to garments or accessories like bags, shoes or backpacks.  It is a fun and creative challenge which goes beyond just adding LED lights to fabric.  For a primer, you must check out the work of Lynne Bruning. Of course, to make things light up really cool, you need some kind of microprocess ...

Binary metric clock using Arduino

This is a very odd kind of clock, which can easily be made with simple supplies. To begin the explanation, I would like to say that I have always wanted time to be metric. 5 o'clock would be mid-day, 7:5 would be three quarters (6:00 pm), and so on. This prototype tells deci-days, centi-days, and milli-days, in that order. For those that are unfamiliar, ten deci-days are in a day, ten centi-days are in a de ...

Hard Disk Clock (HDD Clock with Arduino Uno)

This is a fun project that can be done easily and also cheaply. In this instructable we will explain step by step how to make this beautiful POV clock. Used material: Arduino Uno, RTC modul, ULN 2003, IR diode and IR transistor (used like a sensor, more details in next steps) 4 pushbuttons (for controling the clock) TSOP4838 (allows us to control the clock with remote controler) Temperature sensor (DS18B20) ...

Design Notes: 60V, Synchronous Step-Down High Current LED Driver

Introduction The meaning of the term “high power LED” is rapidly evolving. Although a 350mA LED could easily earn the stamp of “high power” a few years ago, it could not hold a candle to the 20A LEDs or the 40A laser diodes of today. High power LEDs are now used in DLP projectors, surgical equipment, stage lighting, automotive lighting, and other applications traditionally served by high intensity bulbs. To ...

Home Automation Using Arduino & Autohotkey

Its been awhile since i last posted something here. Was kinda busy with my university exams & all! Idea for this project was in my mind for very long & i don’t think anyone would’ve done this project with Autohotkey! Anyway, this is a necessity for me, honestly i’m a super lazy person   & i don’t like getting up to switch on fan/light even though the switches are just 3 footsteps away!   From th ...

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 ...

Twist Shield for the Arduino

This little ‘Add-on’ board allows you to 'Twist' an existing Arduino Shield 90 degree from its original footprint Twist Shield.brd42 KB Step 1: The Problem... Have you ever finished a project and then realized you stopped one step too soon? While plugging in various shields I have into the ‘Wing Tip Extensions’ I built I noticed an odd thing…display shields needed to be rotated 90 degrees to be of any real ...

Microcontrolled Farm Equipment

Modified BaleScoop(for picking hay bales out of the field) from manual levers to arduino controlled functions. This eliminates the need for 3 sets of hydraulic hoses to only one set and operator can focus more on where they are going rather then controling the implement. This is set up for a "Field Mode" and a Travel Mode", and has 3 switched to still control the implment manually to unload the bales or ali ...

Turn your Arduino into a Magnetic Card Reader

Everyone has used a magnetic card reader, I believe. I mean, who carries cash these days? They're not difficult to get your hands on, either, and during a trip to my favorite local electronics shop, I found a bin full of these guys. So....of course, I picked one up and brought it home to see what sort of stuff I could do with it and an AVR. This instructable will show you how to connect a Magtek magnetic ca ...

Arduino PID Motor Controller

INTRODUCTION : The development of high performance motor drives is very important in industrial as well as other purpose applications.  Generally all high performance motor drives use quadrature encoders and PID control because of its simplicity and precise control.  The quadrature encoder acts as a feedback from the motor, it is connected to the microcontroller for furthur processing. With the use of Ardui ...
