Today I test fit all the electronics to make sure everything will work. I initially wanted to place a red led for the BioID and realized that the Arduino Nano was in the way! After about 10-15 minutes of trying to find a solution (and a bit of panicking) I realized that the Arduino Nano alreay has a red LED on the board and by pure luck, it was just beside the BioID lens position... A quick test confirmed that the light would emit through the hole! What a great solution, no soldering required for this small detail!
