We are using an Atlas Scientific ORP probe to take mV readings from different ppm chlorine solutions. We wired up our LCD screen in order to display the values along with the ORP sensor. We pieced the code together and we are certainly not professional coders...after placing the ORP sensor in the calibration solution and running the code, the LCD screen works perfectly displaying the mV values for about 30-45 seconds until the serial monitor on the computer STOPS displaying values, therefore the LCD screen starts repeating the last value over and over again scrolling across the LCD screen.
I am attaching the code we are using along with pictures of what it's doing exactly..
any help would be greatly appreciated, please let me know if you need additional information.
