Hi,

I need help for my project on alarm system for the programming part. Now, what i want to do is just as below :
input -sensor, switch
output = LED
PIC - 16F877 being used


if Sensor is on, Switch(Reset) Off, LED ON
if Sensor is on, Switch(Reset) ON, LED OFF

Below is the program i write, but no matter how i try/ edit the program, it is not working. Can anyone provide me a program for it or tell me wat wrong with my programming!!please help me!!!
Thanks


#include <pic.h>

__CONFIG(0x3F32);

#define sensor RA0
#define sw RA1
#define buzzer RC4

void main (void)

{

ADCON1 = 0x06;

TRISA=0b11111111;
TRISC=0b00000000;

sensor=0;
sw=0;
buzzer=0;

while(1)
{

if ((sensor == 1) && (sw =0))
{ buzzer=1;}
else if ((sensor == 1) && (sw =1))
{ buzzer=0;}
else {buzzer =0;}
break;

}
}
 

remove the break and try. i think that may be the problem
 

hi there,

if ((sensor == 1) && (sw =0))
{ buzzer=1;}
else if ((sensor == 1) && (sw =1))

As I understood you`re trying to check sensor AND sw, ok? If so, you must use "==" instead "=", ok?
In other words (sw == 0).

just trying to clarify better. When you use = you are assigning a value to variable, and when you use == you`re testing a condition.

best regards
