Im trying to upload a sketch to my standalone breadboard Arduino. Im using my Arduino Uno as ISP. Im am using this setup.
The Arduino IDE says Upload finished but gives this error at the same time:
avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check.
I double checked the connections several times?
Any ideas what I'm doing wrong?
I tried adding a cap between Reset and GND but it just gives the same error?
