For this assignment, I programmed my Arduino board to read the inputs from our flame sensor, which is a resistor that varies in resistance based on the amount of UV light it receives. So, once the Flame sensor receives enough UV light, the Arduino board recognizes that there is a flame nearby, and will activate the Relay which is used to power a fan to put the fire out. The relay setup is normally open, meaning that the fan is not receiving power, but once the value coming from the flame sensor gets to a certain point, it sends power to the relay which closes the loop, powering the fan.
