My project is to determine the wind direction which are N,NE,E,SE,S,SW,W,NW by using 3 IR sensor,S,SI and SZ. The IR sensor is to check whether there are input or not. There are 3 LED, L,LI and LZ. When the IR detect input, the LED will on. The result will show in LCD.
The microcontroller im using is PIC16F877A with MPLAB IDE and hiTechC compiler.
Three sensor can work well at first. The second time when i compiled the code, the second sensor (SI) cannot function. LED light is also off. But when i connect the circuit to other pin it is functioning. Anyone can help me to check is it my code problem?
