Hi all, I have tried to combine 2 sketches into 1 but no matter what I try nothing is working. I am posting the code so everyone can take a look at it. I believe i have it in the right spot but at this point I just don't know. It compiles with arduino 23 and I load it in and the time still works. This part I cannot figure where to put in:
void printTemp(void) {
double fTemp;
double temp = Thermister(analogread(0);
lcd.clear();
lcd.setCursor(0,0);
lcd.setCursor(0,1);
ftemp = (temp * 1.8) + 32.0;
lcd.print(fTemp);
lcd.print( "F" );
}
void loop(void) {
printTemp();
delay(1000);
}
here is the full sketch
