Question

A security system uses sensors at every door and window which will set off an alarm if any one of them is opened. There is also a keypad by an entry door to turn on or turn off the system. Describe how these components can be wired in a combinational circuit to provide the needed security.

Answer 1

You have a raspberry pi connected to all the sensors and a code running to  trigger if the sensors are triggered. Each sensor and keypad would run to a different input on the pi. They should al be able to be powered with a single cell lipo. Is that what you are asking?
