I am doing project and I used optical mouse IC sensor M116504386 with 16 pins and I don't know how to get this sensor libraries to interface it with arduino uno.

  • When I google "M116504386", I get 2 results in Chinese. Is this the sensor you are using? sparkfun.com/products/retired/12907 Can you tell us which library you're using? – VE7JRO Jun 21 at 21:57
  • do you still have the mouse? ... if you have it, try to determine the schematic diagram of the mouse – jsotola Jun 21 at 22:15
