Write some Arduino code

I would like to combine 2 pre written codes by Adafruit and expand them for further features.

One is a Arduino master writer RFID, which needs to send the Card details through i2c to the Arduino Slave writer

The second would be a Adafruit data logger with temperature and light reading, this code has a fault which does not print the correct temperature and light reading.

[url removed, login to view]

With this datalogger it needs to be connected with i2c to become a slave writer

It also requires 6 extra pin states, when switched to high, it will set a time, date, temp, light and pin recored to SD

If card is detected it will a write card number with a time, date, temp and light stamp and Record to SD Card.
