PAN3401 y PAN3101 - A2636 pinout

Pinout con arduino:

PIN 7 - SCLK    a digital 2 de Arduino
PIN 8 - SDIO    a digital 3 de arduino
PIN 4 - GND     a GND de arduino
PIN 5 - VCC     a VCC de arduino


Codigo:

// This example reads out the PixArt PAN3101 Optical Navigation Sensor
// It's used in many cheap optical mouses.
//
// For support for the Agilent ADNS-2051, ADNS-2083 or ADNS-2610, move
// the files for your mouse to the folder with the OptiMouse files.
// Then uncomment the right header files and object instances below.
//
// The Arduino will keep track of a (x, y) coordinate by increasing
// or decreasing the x and y variables by dx and respectively dy.
// Every 128th sample it reports the current (x, y) over the Serial.
