Download Microcontroller Based Self-Maintained Aquarium Using PIC16F877

Hardware Component
Microcontroller - PIC16F877
The PIC16F877 microcontroller was used for the main functions of the
aquarium. It controlled the activation of every function according to the program
that was coded and embedded. The output ports of the microcontroller were
connected to the functional components of the aquarium which are the: motor
pump, compact fluorescent lamp, filter, feeder and dechlorination.
The output of every function was controlled by the hard coded program
of the microcontroller. Output will also be dependent on the input of time, fish
count, and day counter that is settable by the user. Refer to Appendix A, for the
figure.
LCD - Hitachi HD44787A (4x20)
The LCD used is Hitachi HD44787A. The size 4x20 is second to the
smallest available in the market. It will be sufficient for the display of information
needed by the user. This will display the important information about the
functionalities of the aquarium like the pH value, the time, and the functions that
are currently working. For the figure, refer to Appendix C.
