+## Description :
+Since , RPIs got no analog I/O pins , you cannot get direct analog mappings using the PI , so in order to read analog mappings ```0~1023``` as a hardware mapping or ```0%~100%``` as a pulse duty cycle , you will need to convert analog outputs to digital inputs through SPI (Serial peripheral Interface) of the PI
