Help. Using Arduino as a pressure and voltage sensing switch? Answered

could use some assistance here.

Required: An activation switch that relies on two pressure sensors and a voltage sensing input and a manual activation switch

I am trying to use an arduino as the mastermind to activate a relay based on 3 inputs; 1200-1500psi transducer, 40-60psi fuel pressure sensor and a 4.8v max throttle position sensor.

The Arduino once receiving an input from my arming switch, will check the sensors/inputs and if values are met will send an activation voltage to the relay, which will in turn activate my nitrous oxide and fuel solinoids.

I may consider adding a small LCD to show what is ready and if the system is armed and activated.
