Here is a fun little project we desgined with the 2017 Eclipse in mind. This project will act as a monitor and data recorder for Temperature, Humidity and light level and report a reading every 5 seconds.
The data will be relayed back you you computer via the USB cable and into the serial mointor. Data can easily be copied and pasted into a spreadsheet for a cool graph of the events.
Wiring instructions and information for setting the clock are included in the code. This project can easily be built on the DuinoKit Jr. or DuinoKit Essentials.
//Following line sets the RTC to the date & time this sketch was compiled //Remove the "//" in front of the following line, upload, then replace "//" and upload again. //This will set the clock moodule for the current computer and then retain currentl time when restarted.
