## Step 5: Simple Code for Analog FSR Measurements

This code doesn't do any calculations, it just prints out what it interprets as the amount of pressure in a qualitative manner. For most projects, this is pretty much all that's needed!

/* FSR simple testing sketch.

Connect one end of FSR to power, the other end to Analog 0.
Then connect one end of a 10K resistor from Analog 0 to ground

int fsrPin = 0; // the FSR and 10K pulldown are connected to a0

void setup(void) {
// We'll send debugging information via the Serial monitor
Serial.begin(9600);
}

void loop(void) {

// We'll have a few threshholds, qualitatively determined
Serial.println(" - No pressure");
} else if (fsrReading < 200) {
Serial.println(" - Light touch");
} else if (fsrReading < 500) {
Serial.println(" - Light squeeze");
} else if (fsrReading < 800) {
Serial.println(" - Medium squeeze");
} else {
Serial.println(" - Big squeeze");
}
delay(1000);
}

why you are dividing fsrconductance by 80 and in else part by 30. <br> <br>(if (fsrConductance &lt;= 1000) { <br>fsrForce = fsrConductance / 80; <br>Serial.print(&quot;Force in Newtons: &quot;); <br>Serial.println(fsrForce); <br>} else { <br>fsrForce = fsrConductance - 1000; <br>fsrForce /= 30; <br>Serial.print(&quot;Force in Newtons: &quot;); <br>Serial.println(fsrForce); <br> <br>kindly Explain this part of the code..
very good tutorial about how to interface a force sensor. also, I add this tutorial in my <a href="http://www.intorobotics.com/force-sensors-reviewed-and-programming-tutorials/" rel="nofollow">article about force sensors</a>
Curious if once calibrated at zero, 1/3,2/3 and full scale, do these devices hold as far as remaining consistent? <br> With low linearity, what was the application these were designed for?
A very interesting Instructable. Thanks
Very interesting!
