I've tried the 2 connection types but i couldn't programm my mini168. It allways give the error that i show in the "error_mini.jpg" file (in the attachments). My latest connection you can see on the files mini1,jpg, mini2.jpg and mini3.jpg. I've chose pro mini 5v,16MHZ w/ ATMega168, but it allways give's the same error. I've tried to push the reset button, and nothing, can anyone help me?

Hi friend,
Please keep pushing the reset button on Pro Mini, then upload your sketch.As soon as the LED on the USB converter flash, release the reset button.

Hi, I bought four geetech Pro Mini Atmega 168 5V/16MHz and transmitter Nano USB converter module. Did not get to program, shows the same error. The driver is fresh, checked all the same port, 19200. Tell me what could be the reason? What am I doing wrong? This is my first steps as Arduino, please help.

Hi, no problem! geetech Pro Mini Atmega 168 5V/16MHz was intact. The reason was Nano USB converter. Poorly soldered a 1 contact (TXD) FT232RL, soldered and everything just worked! Thanks for the advice!
