I set up the circuit the exact same way as it is shown here:
And used the exact same code as shown on the website. But when I press the pressure sensor, the numbers on the serial monitor change from 0.00 to 0.05 and back to 0.00 when I release the sensor. If it were working correctly, the numbers should range from 0.00 to 5.00. Any input from the arduino community would be appreciated.
