-The Arduino runs a continuous sketch that has several functions to read values from the sensors while waiting for input from the serial port. The main idea behind the code was to turn the connected devices only when requested by Raspberry Pi. +The Arduino runs a continuous sketch consisting of several functions. Their tasks are to read values from the sensors and control devices connected to the microcontroller.

 The initial setup for Arduino consists of defining the pin status and first temperature request in order to turn the heater on automatically if the water is too cold. The initial setup for Arduino consists of defining the pin status and first temperature request in order to turn the heater on automatically if the water is too cold.
  
-Further code flow is controlled by Raspberry Pi //i.e.// that the microcontroller only responds to the requests sent through the serial port. Firstly there is a ready check performed, then the several values are obtained from sensors, afterwards, the user input from website is applied //i.e.// the settings for feeder, pump, lamp and heater are uploaded and performed. The code runs in continuous loop.+Further code flow is controlled by Raspberry Pi //i.e.// that the microcontroller only responds to the requests sent through the serial port.
