I'm trying to program a Atmega168 Pro Mini 3.3V/8mhz I bought online. I followed a tutorial that walks through the steps of how to program a Pro Mini with an Arduino Uno. However, in their example they are uploading code to a Atmega328 Pro Mini though I don't think it matters.
Anyway, I followed the same steps as they did (namely hooking up Uno's ground -> ground, 3v -> Vcc, Reset -> DTR, tx->tx, rx->rx). When I attempted to upload via Arduino IDE I got the message that the programmer was not responding. I also noticed that the transfer led on the Uno was not lighting up. Did I screw up something? Also, are my hookups correct? I would think tx pin should connect to rx pin, but I just followed the instructions. Would appreciate any thoughts
