|Hi, I have been given a project to design a circuit which will ignite a pyrotechnic flare after a certain sequence of events has been detected. The events which must be detected are:
A specific signal transitions from a short circuit to an open circuit.
A short pulse signal from a separate detector is received.
A 5V logic signal transitions from logic 0 to logic 1.
Additionally, the sequence in which these events occur is unknown.
I have a massive interest in electronics but only a limited knowledge which I have gained from my university course (Physics), so I am struggling to know where to begin with this project. I need advice on which components the circuit should contain in order to detect these events and if wiring them in a particular way may work better than others.
