I think the nothing sketch - has nothing to do with it - and makes no sense. Probably loose wiring. Also proper Resistors are needed with the XTAL connected. I solved mine following an alternate post: > " I had exactly this problem. If the atTiny is set for external clock, then the ArduinoISP will not be able to program it without an external crystal. Connected a 16MHz crystal and 2 capacitors and worked perfectly. " Smooth running after fixing these. I had 2 problems: 1. Lousy chinese seller off eby , mixed 225 caps with the 220 cap - so my XTAL was not working 2. The Chinese Eby Breadboard had broken Power strips that needed jumpers to make continuous. ---

iam using arduino as isp for atmega32a chip ..... am getting this error while uploading.. help me to recover thoz error avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. An error occurred while uploading the sketch ---
