Alright, so I prototyped a project I’m working on with my arduino uno R3; everything checked out. Then I bought a 5v 328 arduino pro mini for casing in the actual finished project and a CA-42 nokia phone cord to hack into an “FTDI” cable for uploading the sketch onto the pro mini. I soldered everything together inside the cable for the mod, installed the correct drivers successfully (took forever), assigned the cable to an empty COM port, plugged the cable into my arduino R3 (i’m using the R3 to trouble shoot the cable), and uploaded a sketch using Arduino IDE 1.0.1. The arduino powers up, but upon upload I get the common communication error: avrdude: stk500_getsync(): not in sync: resp=0x00.
These are the tutorials I used:
I check’d and made sure all my solder joints have proper continuity and don’t touch. I “loopback’d” the RX and TX pins on the arduino R3 by itself and they check out. I then loopback’d the RX and TX pins on the actual “FTDI” cable using hyper terminal and they check out. When I alligator clip the RX end of the “FTDI” cable to the arduino’s TX pin and the TX pin of the “FTDI” to the arduino’s RX pin the serial monitor show’s no communication. They both check out separately, but when I put alligator clips between the two they no longer communicate…i’ve tried multiple alligator clips and multiple COM ports as well!
Not sure if this is in the right place, but please heeelp!!! I can post pictures if need be.
