How to Upload Sketches to the ATiny2313
This video shows you the setup & programming of the ATtiny 2313 Microcontroller from ATMEL. All you need is a breadboard, jumper wires and an Arduino UNO (or older Duemilanove, but a resistor is needed between RESET & 5V after you upload the Arduino as ISP sketch). This principle can be used with other ATtiny chips, as the pin names are: 13 – SCK 12, MISO 11, MOSI 10, TARGET RESET.
GET CODE for the datasheet which can be used to program other chips.
