Hello, I am new in Arduino programming .Please see below my code. its very simple but its not working. Actually I want to develop one zone fire system with one rely & LED output. Please see below my code. Its not working any thing,
Program :-
/* One Zone Fire Alarm Panel * one momentary switch is connected to pin 2, RED led connected to pin 13 & one relay connected to pin 3; * Working:- 1) When switch_Fire will press first LED will glow continuously as well as relay will also turn ON till manual RESET button not press by user 2) If fire is there i.e. LED anf relay are activated and if some one press bypass switch than only Relay will turn OFF but LED is going ON till reset 3) If first press bypass switch (monetary) and fire will occurs (press switch_Fire) then only FIRE LED will glow but relay will not be activate 4) NOTE :- 500mS debouching delay will use for both fire & bypass switches.

const int switch_Fire = 2; // Pulse / momentary type NO switch connected for fire alarm simulation const int bypass = 3; // Pulse / momentary type NO switch connected for bypass alarm const int Fire_led = 13; // Alarm RED LED is connected for visual indication const int Fire_Rely = 4; // One relay latch-able connected if fire occurs or switch_Fire will press
int switch_Fire_state = 0; // Store switch_Fire status int bypass_state = 0; // Store bypass status unsigned long debouching_delay = 500; // set debouching delay at 500mS for avoiding false alarm activation
void setup() { pinMode(switch_Fire, INPUT); // Set switch_Fire as a input pinMode(bypass, INPUT); // Set bypass as a input pinMode(Fire_led,OUTPUT); // Set Fire_led as a output pinMode(Fire_Rely,OUTPUT); // Set Fire_Rely as a output
}
void loop() {
switch_Fire_state = digitalRead(switch_Fire); // Read switch_Fire switch status and store in "switch_Fire_state".
if (switch_Fire_state == HIGH) {
int value = millis();
if ((millis() - value) > debouching_delay) {
fire(); // call fire function } }
bypass_state = digitalRead(bypass); // Read bypass switch status and store in "bypass_state".
if (bypass_state == HIGH) {
int value = millis();
if ((millis() - value) > debouncing_delay) {
bypass_function(); // call bypass function } }
}
void fire() // fire function use for taking action if "switch_fire" switch will press {
if ((switch_Fire_state == HIGH) && (bypass == LOW)) {
int value = millis();
if ((millis() - value) > debouching_delay) {
digitalWrite (Fire_led, HIGH); digitalWrite (Fire_Rely, HIGH); } } else { digitalWrite (Fire_led, LOW); digitalWrite (Fire_Rely, LOW); }
}
void bypass_function () // bypass function use for taking action if bypass switch will press
{
