I ordered my EC and pH sensors from Atlas Scientific.
I am trying to get both my sensor to work.
EC Empty test
Uploading setup(){} and loop(){} and having TX and RX plugged into pin 1 and 0 gets me a continous reading on the serial monitor.
EC Sample Code (EZ_com.ino from their site)
I plugged TX into 3 and RX into 2. Uploaded on my Uno. Serial Monitor is blank. Tried typing "C" or "c" but still no change. Upon further investigation, I added this line right before the while loop, Serial.println(myserial.available() ? "yes" : "no") - the answer is always a "no".
pH sensor
The same can be said for my pH sensor: empty test works, but the sample code doesn't (I've turned arduino_only=1, too). Serial.println(myserial.available() ? "yes": "no") is always a no.
Why are neither of these sensors available? I am just running sample code from their site.
