dear all...i have construct a code for 4 way traffic light.please help me with the code
| Code: |
#include <16F84.h>
#define R1 PIN_A0
#define Y1 PIN_A1
#define G1 PIN_A2
#define R2 PIN_A3
#define Y2 PIN_A4
#define G2 PIN_B1
#define R3 PIN_B2
#define Y3 PIN_B3
#define G3 PIN_B4
#define R4 PIN_B5
#define Y4 PIN_B6
#define G4 PIN_B7
void main ()
while (1)
{
output_high (R1);
output_low (Y1);
output_low (G1);
delay_ms (1000);
output_high (Y1);
output_low (R1);
output_low (G1);

}

it gives an error like this:

What value of resistors do you have to limit the LED currents ?
PIC pin ---A-|>|-K--/\/\/\/\---- gnd. |

| I'd probably use 330R resistors. |

Hi,
This is a simple project, and with the circuit right in front of you, aren't you in the best position to find the problem yourself? At the very least, provide some basic diagnostic info to the forum to give us something to go on.
Earlier it was assumed that your "lamps" were really LED's. Is that true? If so, are they all connected the same way? Can you try a very simple version of your code that flashes a single LED in a loop? Can you try another simple program that lights a different LED? When the LED is supposed to be ON, can you measure a 'high' output value on the PIC output pin? Perhaps you have damaged your PIC by not using current limiting resistors initially? Can you try another PIC?
Finally, you never posted your Fuses, or your compiler version. It's possible that you PIC is not even running correctly. If you post a complete program we can try it out!
