I have made severals programs for Photon, and Argon devices, how ever I can´t undestand how the Tracker One works since the tytical ¨c¨ structura appear a little diferent. Any one on this community know how to add to the tipical default software a analogue tipical information port ( using the internal ADC port 3) for connect a analogue sensor as a light sensor, or any other analogue sensor and publish this information with the ubiquity information at the same time?.
Your Tracker One firmware is typically based on the TrackerEdge firmware so the built-in functionality still works.
From that base, you simply analogRead(A3) from your code like you would on any other device.
The pin is exposed on the M8 connector, along with GND, which you can use to feed a 0-3.3V analog signal.
