This Simulink Model uses the S-Function Builder to program a Data Logging Shield attached to an Arduino UNO.
It is makes use of existing C-code by Adafruit Industries (see below link), and shows how to integrate it into Simulink.
The data logger is portable and enables you to log sensor readings based on the sample time you set. The shield houses a real-time clock (RTC) that is powered by an external battery. This means that the clock is continuously ticking, regardless of whether the board is powered up or not. Data is logged onto an SD card in .csv format.
You can connect the external circuit to an LDR to log light intensity in a room. Alternatively, you can utilize other sensors.

An updated submission is available here:
- Easier to add the include lines for the libraries.
- Eliminates the need to keep re-building whenever a change needs to be made to the code.
