I'm using a 1kg Load Cell which I bought here near our place.
And i use this blog as a reference: http://cerulean.dk/words/?page_id=42
in the place where I bought the loadcell, they don't have INA125P which is needed. That's why I bought a equivalence IC of this which is INA114P. I research the data sheet of INA125P and INA114P and base from this. I connect the Pin to INA114P. And use the Code:
int weight = analogRead(0);
But the problem is. The program only shows two outputs in the serial monitor. And it is if a large amount of weight is applied and when there is no weight or low amount of weight is applied.
Example Output if there is weight applied
Example Output if there is no weight applied
For your reference here is the connection that i made with my IC and loadcell.
Arduino Analog 0 -> pin 6 IC
Arduino 5v -> pin 7 IC
Loadcell (Red) -> 5V Arduino
Loadcell (Black) -> Gnd Arduino
Loadcell (Green) -> Pin 3 IC
Loadcell (White) -> Pin 2 IC
Resistor -> Pin 1 and 8 IC
Please Help me.And Thanks
