Hi All & thanks in advance for any help. My arduino doesn't recognise my pH sensor.
I am a level 0.01 Arduino programmer. I have bought an Arduino Uno + pH testing kit (this one)
I found this source code & have uploaded it to my board + connected the pH sensor to the outside ICSP ports, simply because that's where they look like they should connect.
Now in the serial monitor, I get 25*/pH1.xx readings, but alas I get the same scrolling text even if I unplug the pH sensor from the ICSP port.
I guess the code is looking at a different port? Can someone point me in the right direction to get the pH sensor properly connected? Again, very amateur user so simple explanation preferred.
