I have recently bought an Arduino MINI wich doest not have an USB to up-load the Sketch from the PC.
As I already have an Arduino MEGA 2560, I have tried to use it as an "USB to TTL" adapter but without success.
I have conected:
5v to 5v GND to GND Rx to Tx (also tried with Rx) Tx to Rx (also tried with Tx)
Reset to GND in MEGA. But it does not work.
I have got error mesages like: "avrdude: stk500_getsync(): not in sync: resp=0x00"
Somebody could help me
