Not sure if I'm doing something wrong. I've hooked up my breadboard and Arduino to monitor the temperature using a thermistor. But here is the output of the serial monitor:
åòäòààúÿååäàäÿÿòòäÿòåðåðÿäñðñòÿàÿñãñýãñãàãññãñãäààâââñãäÿäñàÿñòàÿàäâñààÿÿÿàâàÿÿååäðäðð
So what do you think?
Here is the code:
#include <math.h> //loads the more advanced math functions
void setup() { //This function gets called when the Arduino starts
Serial.begin(115200); //This code sets up the Serial port at 115200 baud rate
}
double Thermister(int RawADC) { //Function to perform the fancy math of the Steinhart-Hart equation
double Temp;
Temp = log(((10240000/RawADC) - 10000));
Temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * Temp * Temp ))* Temp );
Temp = Temp - 273.15; // Convert Kelvin to Celsius
Temp = (Temp * 9.0)/ 5.0 + 32.0; // Celsius to Fahrenheit - comment out this line if you need Celsius
return Temp;
}
void loop() { //This function loops while the arduino is powered
int val; //Create an integer variable
double temp; //Variable to hold a temperature value
val=analogRead(0); //Read the analog port 0 and store the value in val
temp=Thermister(val); //Runs the fancy math on the raw analog value
Serial.println(temp); //Print the value to the serial port
delay(1000); //Wait one second before we do it again
}
