I want to use Arduino(atmega8) on breadboard using USBASP programmer and want to use Serial Monitor without using any Arduino board as ISP programmer. My questions: 1. Is such thing possible? 2. How do I do that?
How to use Serial Monitor without Arduino board?
Yes that is possible. Connect to the RX/TX pins on the breadboard chip. Remember these are 5V. You will need an Serial-USB or RS232 adapter to connect your development machine. Please see this blog post for some inspiration.
