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 […]

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

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

Intro: My Nikon DSLR has an infrared remote function (remote sold separately) that is really handy, but fairly limited in range. A while ago, I bought a TV-B-Gone Kit from it’s inventor Mitch Altman, and it can turn TV’s off from a great distance. I thought, “Hey, this thing is open source! I can hack

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

This project will display the temperature and time over the LCD display. LM35 is used to sense the temperature and the analog out of the LM35 is converted to digital by using the inbuilt ADC on the ATmega16 chip. An software clock is generated and the Time is also display. Download the Bascom code and

Description With this small board you can program most of the AVR ATTiny microcontrollers or you can build your projects to use it in a stand alone application. It can be powered with a 9V battery because it has 5V voltage regulator on it. The voltage regulator can give 1000mA current. The power to the
