The exact valuein [index11] will determine the sensitivityof the led’s to the sound.8 x Light sensor L 0-255 Light sensor in left eye – A/D value 0-2559 x Light sensor R 0-255 Light sensor in right eye – A/D value 0-25510 x Sound MP3 0-255 A/D measurement of sound pressure –coming from the MP3 sound module.11 Sensitivity x 0-255 Sensitivity of the led’s of the mouth tosound. How larger this value – how moresensitive it will be – usually a value of 50is a good starting value.This sensitivity can also be changes by apotentiometer on the PCB of the head.Bart Huyskens Manual Elektor Proton V1.0 3 April 2011 63
