Erni:
I have a pin on AtTiny connected to the Rx pin on arduino UNO
And the ground pins ?
with capacitor over reset and gnd
No it should be either
- A jumper wire between reset and ground (and a small resistorr on the tx/rx lines for safety)
or- remove the processor from your UNO board
Got it working. Thanks! Can't believe it was just a wire instead of a capacitor.
