The PR and ST pins on the Genie chip are Serial In and Serial Out respectively.
Now time to comment on the rest of your circuit:
- The voltage regulator is connected backwards. The input is also connected to the output.
- You have no 'bulk capacitor' on the output of the voltage regulator (normally 100µF).
- Only one of the two 0V pins on the microcontroller are connected.
- You are using NPN transistors as high side drivers - that will not work.
- The 220 ohm resistors on the transistor bases seem to be low for base resistors - are these really the required base resistors?
Also an LDR is not an on/off motion sensor but I've kept that off the list above because you're probably just using it to represent a motion sensor.
