    - The Ploopy Mouse will either be completely dim, or there will be a white LED that is either very dim or very bright. Any of those are normal states.

+3. Remove any capacitor between RST and GND on the Nano, and then open up the ArduinoISP sketch in Arduino IDE (in `File -> Examples -> 11.ArduinoISP -> ArduinoISP`).
 4. Upload the ArduinoISP sketch onto the Arduino Nano.
    - Make sure that, in the Arduino IDE, `Tools > Board` is set to `Arduino Nano` and `Tools > Programmer` is set to `AVRISP mk II`.
