Programming ATtiny85 With Arduino IDE & Arduino Uno as ISP

It's possible to transfer your Arduino sketches on ATtiny85 by using Arduino Uno (in this example) as ISP programmer.

Setup:

  • Upload "ArduionISP" sketch (which is found in default Arduino examples) in to your Arduino. Now it became programmer, than do the connection below.
  • Download ATtiny board definitions and install like; Documents > Arduino > hardware > attiny > avr
  • Select
    • Tools->Board->ATTiny
    • Tools->Clock->8Mhz (internal)
    • Tools->Processor->ATTiny85
    • Tools->Programmer->Arduino as ISP

Connections:
