im building a circuit which simulates an automobile black box of a vehicle. The system models the black box by using a microcontroller to interact with a signal representing the airbag deployment module. If the signal is high, the microcontroller is to interact with signals from a switch representing the brake lights and record this event - recording it as "brakes depressed" and also interact with a potentiometer used to model speed measurement and record the speed measured. To me this sounds really complicated. I need some insight into how my circuit is gonna look like and what other components I may need apart from the switches.
