SD
Write Data to a File on the SD Card
This block writes data to a file on the SD card when using the SD module.
Below are the steps that occurs:
- Opens a file on the SD card. If the file is opened for writing, it will be created if it doesn't already exist (but the directory containing it must already exist).
- Print data to the file. Optionally, a new line (return) is appended after the data if NewLine is true.
The inputs are as follows:
- Filename - The name of the file to open in the SD card which will be written to.
- Data - The data that will be written to the end of the opened file.
- NewLine (boolean) - True, will append a Newline (return) to end of Data. False, will skip appending a Newline to the end of Data.

EEPROM
EEPROM is a memory on the Microduino Core modules which can be used as storage for data. Data stored in the EEPROM will be preserved even if the power is turned off and can be retrieved.

Write a Byte
This block writes data (1 byte) to the address on the EEPROM.
- Address - The location to write the Data to.
- Data - 1 byte, which will be written to the EEPROM at Address.

Read a Byte
This block reads and returns data (1 byte) from the address on the EEPROM.
- Address - The location to read data from the EEPROM.

Write a Long
This block writes data (1 long datatype) to the address on the EEPROM.
- Address - The location to write the Data to.
- Data - 1 long datatype, which will be written to the EEPROM at Address.
Note: 1 long is equal to 4 bytes. Therefore, the next available EEPROM address will be +4. i.e.
If writing a long to EEPROM address 0, then the long will consume 4 spots (0 to 3). The next free spot will be address 4. Writing to address 1-3 will overwrite a part of the long.
Read a Long
This block reads and returns data (1 long datatype) from the address on the EEPROM.
- Address - The location to read data from the EEPROM.
