Ok Everyone, i've done some hard work trying to figure out the problem. Everything seems to be working fine. Except the part in the for loop won't be able to print out the statement if it goes less than what i have provided on my 2D Array Table. Here is my current code that i have modified: -
const int ThermPin = A0;
const int rows = 10;
const int cols = 2;
int Table[rows][cols] ={
{ 25, 4470 },
{ 26, 4250 },
{ 27, 4030 },
{ 28, 3800 },
{ 29, 3530 },
{ 30, 3270 },
{ 31, 3200 },
{ 32, 3170 },
{ 33, 3100 },
{ 34, 3070 }
};
void setup()
{
Serial.begin(9600);
}
void loop()
{
float Vin = 5.0;
float ThermResist = 0.0;
float R2 = 10000.0;
float SensorValue = 0.0;
float Vout = 0.0;
/*
Keeps on looping for times everytime i change the if statement to '<=' instead of '==' (e.g. ThermResist <= Table[4][1] provides a printout statement if the thermresist is less than of what it have been provided
in the table. But it doesn't do that, instead it loops the printout result 4 times and then prints out the sensorval, volt, and Ohms.Then it keeps on looping the same output, which i couldn't find an alternative to
avoid this for loop from looping the printout 4 times, as well as triggering the function when it hits below table[4][1]).
*/
for(int i=0; i<rows; i++)
{
for(int j=0; j<cols; j++)
{
if(ThermResist == Table[4][1])
{
Serial.print(Table[4][0]);
Serial.println(" C");
}
j++;
}
i++;
}
SensorValue = analogRead(ThermPin);
Serial.print("Value = ");
Serial.print(SensorValue);
Vout = (((SensorValue+1)*Vin)/1024.0);
Serial.print("\t Voltage = ");
Serial.print(Vout);
Serial.print(" V");
ThermResist =((R2*Vin)/Vout)-R2;
Serial.print("\t Resistance = ");
Serial.print(ThermResist);
Serial.println(" Ohm");
}
