I made this arduino for a school project but I can't get it to work. In fact I can't upload sketches into. That's what I have: - Arduino serial2USB light adapter ( http://arduino.cc/en/Main/USBSerial) - My custom arduino PCB - Arduino 1.0.5
What I'm trying to do: I'm trying to upload a sketch on it using Arduino IDE and Arduino's Serial2USB Light Adapter.
Error I get on Arduino IDE avrdude: stk500_getsync(): not in sync: resp=0x00
Notes - Drivers are installed correctly and COM is successfully set. - ATMEGA 328P-PN is already programmed with Optiboot - When I press Reset button nothing happens.
SERIAL- PCB CONNECTIONS 5V- 5V GND-GND TX-RX RX-TX RESET/EXT- DTR
If you need further informations please ask :) Thank you for your help
