Using Arduino R3 to program ATtiny85 chips

I would like to program ATtiny85 chips with the Ardunio R3 board, as described on “http://hlt.media.mit.edu/?p=1229”.

I’m getting this error: stk500_recv(): programmer is not responding

I am using Arduino 0023 software with attiny45_85.zip files installed as per Arduino instructions.

I tried these steps:

  • Downloaded BLINK program to Arduino on a MacBook Pro and on a Windows 7 laptop

  • Selected ATtiny85 (w/Arduino as ISP) before trying to program ATtiny85 chips

  • Tried several different ATtiny85 chips

  • Tried a second Arduino R3 from Radio Shack (same error as the Arduino R3 from SparkFun)

  • Verified all wiring as per MIT instructions

Does anyone have any suggestions?

I didn’t see it in your list of things you did, but you need to first upload the “ArduinoISP” sketch to your Arduino with the R3 selected as your board. Then switch to ATtiny85 (w/) and flash the blink sketch. Note that you may also need a 10uf capacitor between the RESET and GND pins on the R3 if you get an error after that. Negative side of the capacitor goes to GND I believe.

Thanks for the quick response. I don’t know how I missed the step to upload the ArduinoISP sketch. :oops: Everything is working great now!
