The issue I am facing is that I am unable to obtain any results while attempting to calibrate the conductivity sensor using Arduino Uno and the EC EZO circuit. Despite connecting the conductivity sensor with the EC EZO circuit and running the provided Arduino code (available at https://files.atlas-scientific.com/Arduino-Uno-EC-sample-code.pdf), I have been unsuccessful in obtaining any output. Although I have checked the connection and observed that the EC EZO circuit's LED is blinking, the problem persists. Can you suggest any solutions to overcome this issue?
What kind of output? Please post the sketch here, in code tags, not as a link to a PDF document. Also, a wiring diagram.
