This instructable will show you how to read the number on a binary pushwheel or thumbwheel switch using LED’s or an AVR microcontroller (I’m using an ATmega328p but this can be adapted for any AVR or probably another microcontroller of your choice). Multiple thumbwheel switches can be strung together to make an electronic combination lock, […]

So, you’re going to a conference/meetup/nerdfest and you want to do something that sets you apart from normal people.  An LCD namebadge powered by an ATtiny2313 is a great way to do that.  This is a general purpose LCD display unit powered by a 9V battery and a simple voltage regulator circuit (the same 7805 […]

The Arduino — and AVRs in general — have a wide range of power supply options ranging from around 1.8V to 5.5V. The choice of voltage is usually determined by the desired clock speed or power consumption requirements. The Arduino and its many variants have power jacks that allow connections from big, clunky “wall warts.” […]

This tutorial will step you through the process of creating a set of controllable and configurable traffic lights whilst also teaching you the basics of Arduino. Some knowledge is needed and I highly recommend reading and following through on most if not all of the pages of the following document, created by the wonderful Arduino.cc […]

Valencia, CA (PRWEB) November 30, 2011 The Naztech Dual USB 3-in-1 Charger, also known as the N321, was honored with a 2012 CES Innovation Award in the Personal Electronics category by the Consumer Electronics Association (CEA). From countless products and companies, a distinguished panel of independent industry experts, engineers, designers and trade media were assigned […]

As most guys I don’t tell my wife that “I love you” as often as I should, but this little gadget will at least improve that situation as bit. So by combining a nice box and some hardcore electronics nerdiness I’ve made a nice christmas gift for my wife. The LoveBox is a small box […]

In this, my first Instructable I’m going to show you how to make a stripped down Arduino for a fraction of the price, using Stripboard/Veroboard. Material List: 1x Atmel ATMega168 = �2.65 1x Stipboard = 72p 1x 7805 Voltage regulator = 26p 2x LEDs = 16p 2x 220 Ohm resistors = 8p 1x 10k Ohm […]

The game Mastermind has been around a long time, and I remember getting a board version with colored pegs when I was a kid. I love this game, as it is solvable simply by pure logic. One player (or a computer/microcontroller) chooses a sequence of colors from a pool of available colors and then the […]

Building a stand-alone AVR ATMEGA project sometimes leaves you with no easy to read output from your project. But you can use an Arduino to act as a communications bridge between your embedded project and your PC’s Serial Monitor program! I’m building an embedded multi-channel thermocouple reader/datalogger, which has a lot of connections and soldering, […]

Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards. Using attiny2313. Step 1 Scheme Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller. Step 2 Bottom view […]
