2) A door control system has three entrances. There is 1 PIR sensor, 1 LDR and IR receiver on the door. Requirements: If the PIR sensor detects movement while the air is bright the door will open. If the PIR sensor detected movement while it was dark, it will be checked to see if the correct signal is coming from the IR receiver, and if the signal is not received, the door will not open. The door will open if the PIR sensor detected movement while it was dark and the 0x12345H signal came from the IR receiver. i) Draw the block diagram of the system and the location of the sensors. (10 points) ii) Draw the connections of the circuit you created. (15 points) iii) Write the necessary code for the correct operation of the system. (25 points)
