Hello, I want to connect this clone of Arduino Pro Mini to PC. I plugged it correctly and set it up in IDE too.
Here photo of it and screen of error message. I got a RS232 converter to connect. Please help.
That converter cable doesn't have a DTR or CTS line so it won't do auto-reset. This means you will need to press the reset button on the Pro Mini at the right time every time you want to upload to it. I recommend buying one of the breakout boards that plug right in to the Pro Mini and will do the auto reset so you don't need to do it manually.
