Hi, recently i bought a new arduino lilypad and pro mini boards with atmega168.
I use a usb to serial adaptar like this:
An when y try to upload the sketch de pin13 led blink normally and the rx led of the serial adaptar blink three times and the arduino ide said thar the board dont comunicate with the computer. I have the problem with both boards. I use the arduino 1.0.2 and i review the port and the conexion with rx and tx with the board and the serial adaptar and nothing change. i also tried using the arduino uno board without the chip as usb to serial adaptar and hte problem persist. I dont know how to fix the problem. The correct board and port is selected in the arduino IDE and dont work.
