Adding autoreset feature to Arduino NG rev.c
Arduino NG needs you to press the RESET button before you can upload a new sketch. If you fail to do this you will get a stk500v1 upload error. The reason is that Arduino's boot-loader is giving way to last downloaded sketch after 10 seconds. For starting a new upload you need the boot-loader running so you need a reset just then.
arduino-0009 uses DTR pin 2 on the FT232RL chip to reset the micro-controller. A 0.1uF capacitor as the one shown in the picture will do the work.
Please note that till now arduino website is giving you the wrong information, telling you to use RTS (the two pins below my capacitor) which is NOT working with arduino-0009 environment.
