If 'im not wrong that capacitor goes between GND and the RESET pin. On the BT case PIN7.
"We’ll also connect a 10 uF capacitor between reset and ground on the Arduino board as shown in the diagram (the stripe on the capacitor that’s marked with a negative sign (-)."
According to: http://hlt.media.mit.edu/?p=1706
But what worries me most (allow my ignorance) Is this part:
"The capacitor prevents the Arduino board from resetting (which starts the bootloader), thus ensuring that the Arduino IDE talks to the ArduinoISP (not the bootloader) during the upload of sketches."
Since the Arduino BT uses soldered 168 MCU, i'm afraid of breaking/corrupting the bootloader...
I'm ready to try to flash some ATTiny85 i got, but since this is my only arduino board, and it was not that cheap.. I'm a bit doubtless.
Could you help me understand better the real risks?
Thanks in advance,
