Jar of Fireflies using AVR ATTiny45 Microcontroller

This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and

I2C Bus for ATtiny and ATmega168

I love the Atmel AVR microcontrollers! Since building the Ghetto Development System described in this Instructable, I’ve had no end of fun experimenting with the AVR ATtiny2313 and the ATmega168 in particular. I even went so far as to write an Instructable on using switches as inputs, and extended the Ghetto Development System concept to

16-key Keypad Decoding with an AVR MCU

This instructable will show you how to interface a 16-key keypad to your AVR microcontroller and read the key when a key is pressed. I’ll introduce the keypad first, then the 74HC922 16-key decoder IC as a pin-saving mechanism, then finally how to take the data and massage it so that you get the correct

Repair dead AVR's – Attiny fusebit doctor (HVSP)

Did you make a mistake while programming fusebits, or purposely disabled reset pin (RSTDISBL) or ISP programming (SPIEN)? No need to buy or make inconvenient HV programmer only for unlock couple of Tiny AVR’s. This Attiny fusebit HV doctor will cure your dead tiny microcontrollers, by restoring all fusebits to factory settings – nice and

How to Read Binary/Hex Thumbwheel Switch with an AVR Microcontroller using ATmega328p microcontroller

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,
