Design an alarm with two pushbuttons, a photoresistor, and a buzzer. Have one push-button act a snooze for 4 seconds and the other to turn off the buzzer.
My Photoresistor is attached to Analog Pin (A1), the Piezo/buzzer is attached to (PWM pin3), Pushbutton one is attached to digital pin(7), and the second buzzer is attached to digital pin (8).
MY CODE: I have the photoresistor figured out, just need help with the two push buttons. Please Help!
clear; clc;
a= arduino();
count= 0;% staring button % Snooze = 0; %inital state
Snooze=0
Off= 0;%inital state
while true
v = readVoltage(a,'A1');%photoresistor
disp(v);
if v >= 4
playTone(a,'D3',290,'on');%buzzer
end
Snooze = readDigitalPin(a,'D8'); %snooze 5 sec
if Snooze == 1 && Off == 0
playTone (a,'D3',290,0.5);
end
end

For the snooze button, check if it is pressed and use the "pause" function to delay the buzzer for 4 seconds. For the off button, set a flag when it is pressed to stop the buzzer. Use this flag in your loop to decide whether the buzzer should sound. You can find the documentation for the "pause" function here: https://www.mathworks.com/help/matlab/ref/pause.html.
