Transform a cheap RC Transmitter with Custom Firmware using ATMEGA64 Microcontroller

Leave a Comment / AVR ATmega Projects, Radio Projects / Ibrar Ayyub

The Turnigy 9x is a cheap Chinese radio transmitter widely sold by hobby king and other retailers under a variety of names. This is a computerized radio transmitter and is already a great deal for the price ($53 currently) and pretty capable if you can figure out how to use the stock firmware. The microcontroller […]

Using ATMega328 Microcontroller Custom Tron Disc Mod

Leave a Comment / AVR ATmega Projects, LED Projects / Ibrar Ayyub

In this Instructable, I cover modding the store-bought Deluxe Identity Disc to an upgraded version with 64 leds, controlled by an AVR MCU. The upgraded version is costume-ready and would be an excellent addition to your Tron costume – it’ll also look great on your desk/dresser/etc. My 7 year old daughter watched Tron:Legacy with me

When my little girl was born I wanted to make her a special night light for in her room. I made her a ceiling light with twinkling stars. It is made up of a piece of custom wood with 100 LEDs mounted in it. An AVR AT90S8538 micro controller runs a bascom program that produces

Using max7219 microcontroller Build an electronic score keeper/storage box

Leave a Comment / AVR ATmega Projects, Other Projects / Ibrar Ayyub

The instruction manual for each of the MANY munchkin series of card games always includes a phrase like “you will need a 10 sided die for each player or some other device to keep score.” 10 sided dice are not hard to find in my house, but I took this as a challenge to make

Using AtTiny2313 microcontroller Build an electronic polyhedral die

Leave a Comment / AVR ATmega Projects, Other Projects / Ibrar Ayyub

Dice are fun. Polyhedral dice used in D & D are even more fun, particularly in big handfuls of different sizes. But a handful isn’t always practical. Ever since I saw the dragon bone electronic die wand advertised in the back pages of Dragon magazine when I was a kid, I wanted an electronic device

How to drive a lot of LEDs from a few microcontroller pins

How to drive a lot of LEDs from a few microcontroller pins.

Leave a Comment / AVR ATmega Projects, LED Projects / Ibrar Ayyub

Using the fact that many microcontroller pins have three states (+V, GND, or “high impedence”). You can drive N*(N-1) LEDs from N pins. So the little 8 pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs on its five available output pins, and still have one pin left for some kind of

Using the 8Pin ATTINY programming shield with an external clock

Leave a Comment / AVR ATmega Projects, Other Projects / Ibrar Ayyub

Instructables author extraordinaire Randofo created a great programming shield to use your Arduino to program 8 pin ATTINY processors. He was even generous enough to give 50 copies of it out to people who authored instructables using AVR processors. It works great on brand new ATTINYs and any chip that is programmed to use it’s Internal clock.
