Periodic Table Database

Summary

A database for elements in the periodic table where the user can browse through all the elements, with different UI layouts available to use. This project also has predictive search, using the Trie data structure. The user is able to search for a desired element, even if it's partially correct, the program will print out suggestions that the user can then select from.

Running Instructions

Hardware Components:

• Arduino Mega 2560 Board
• Banana plug wires
• 2 button components
• 2 10k resistors
• Adafruit TFT display

Wiring Instructions

Display Pins	Arduino Pins
1 GND	BB GND bus
2 Vin	BB Vcc (positive) bus
4 CLK	Pin 52
5 MISO	Pin 50
6 MOSI	Pin 51
7 CS	Pin 10
8 D/C	Pin 9
19 CCS	Pin 6

Button Pins	Arduino Pins

In order to correctly run the program, you must first navigate to the source directory with the project files. Navigate to the client subdirectory, then use the command:

make upload

After running the command above, navigate to the server subdirectory and use the command:

make && ./server

The server will be brought online and the program will be running.

How to Use

Once the program is uploaded to the Arduino and the server is brought online, the following user actions are permitted:

• The user can use the left/right buttons to scroll through the cards
• The user can tap the screen to flip the card and see more information
• The user can click the L button to cycle through different layouts, each with different verbosity of information
• The user can click the search button to initiate a search

Search Protocol

Once the user clicks the search button, use the following steps to search for an element:

1. Type in your search string in the terminal when prompted
2. Press enter once your search string is complete
3. If a partial search is entered, select one of the suggestions from the screen
4. The program will then jump to the selected card

Miscellaneous

Makefile (server) Targets

• make (server) : builds the project and generates the server executable
• make serialport.o : compiles serialport.cpp into its respective object (.o) file
• make server.o : compiles server.cpp into its respective object (.o) file
• make clean : removes the .o and executable files from the source directory
• make help : prints out further information about the makefile targets available to use
