Circuit diagram:

2.By cylindrical shade to keep out the LED,and photosensitive receiving tube is for detecting RPI-1031 current state
3.When RPI-1031 rotates to the state shown as below,LED is shadowed by the shade;and two photosensitive receiving triodes cannot receive the light;they will be in off state,output low level;two GPIO ports both output low level
4.When RPI-1031 rotates to the state shown as below,one of the photosensitive triode was shadowed,the light emitted by LED only can be received by the other one;that means above photosensitive triode is on,and photosensitive triode under side is off;then two GPIO ports output respectively output high level and low level
5.When RPI-1031 rotates to the state shown as below,the shade does not shadow;the diode will shine,two photosensitive triodes can receive the light;then all of them will be on,both of two GPIO ports output high level

6.When RPI-1031 rotates to the state shown as below,this state is adverse to description 4;two GPIO ports output level will be intercahnged
