Heatseek Feather Sensor

Building Project

1. Ensure you're on (at least) version 1.6.13 of the Arduino IDE
2. Unzip libraries file and place the contents in your Arduino user libraries folder. (Usually ~/Documents/Arduino/libraries)
3. Set up WICED Feather using steps here.
4. Set up M0 Feather using steps here.

Software

Outline

1. Prompt user to set RTC clock time if necessary. (TODO: set this by web request).
2. If last reading time exceeds reading interval, take a new reading.
3. Store the reading on the SD card.
4. Store the reading time on SD card for comparison against reading interval.

Notes

• Always prioritize logging data to SD card. The microprocessor should always reboot and continue taking readings if there is a problem transmitting the data.
• TODO: Ensure device is not on battery power prior to writing to SD card.
