Question

How might one create a burglar alarm system using the PT5529B-L2-H2-F photo transistor in which a 12 Volt alarm sounds continuously when a person breaks the laser beam? Include a user button to reset the system and turn off the alarm after a burglar has triggered it. Provide a detailed circuit diagram and a brief explanation of operation. Hint: use an SR latch and any other logic gate to provide the logic. Apply the output of the logic to the coil of a 5 volt relay. Use a 12 V battery on the outpout of the relay to power the alarm (similar to how you powered a 120 V lightbulb in the previous lab) Provide a detailed circuit diagram of the burglar alarm system and a brief explanation of operation. Identify the 74 IC number of each logic gate. Label the pin numbers of each logic gate and the pin numbers of the relay.
