Home automation

[mmjatta]

Hi! am doing a simple project on home automation and i came up with a problem with my if statement the print wrong words in virtual terminal...please HELP... below are my code and attached is my circuit.. am using mikroc and proteus.



//Devices pins
sbit buzzer at RD0_bit;
sbit fridge at RD1_bit;
sbit security at RD2_bit;
sbit sitting at RD3_bit;
sbit power at RD4_bit;
sbit sensor at RD5_bit;


// Lcd pinout settings
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D4 at RB0_bit;

// Pin direction
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D7_Direction at TRISB3_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D4_Direction at TRISB0_bit;
// End LCD module connections

unsigned char beeps = 0;
char turn;



void sensing();
void beepBuzzer();

void received(char * receive) //received message from user
{
UART1_Write(13); //<CR> mean Enter
UART1_Write_Text(receive); //Message sent to the user
UART1_Write(13); //<CR> mean Enter

Delay_ms(100);
}

void beepBuzzer(){
if(beeps > 0){
buzzer = ~buzzer;
beeps--;
}
}

void sendTxt(char * message)
{
UART1_Write_Text("AT+CMGF=1"); //select text mode for sms
UART1_Write(0x0D); //<CR> mean Enter
