Write an Arduino program (using PORT,PIN,DDR) for the following question:

A door (active low) is connected to bit 1 of Port B, and an alarm is connected to bit 7 of Port C. Write a program to monitor the door sensor and, when it is active, turn on the alarm.

// if door is active low turn on alarm

void setup(){

//initialize the port pins for inputs and outputs

//enable pull-ups if needed

//default the alarm to off

} //setup

void loop(){

// check if the door sensor is active. If so, turn on alarm

// if not, turn off alarm

} // end loop
