LCD Screens, Navigation keypad and Database security

The team is working with the tasks for the second phase of the project. Laura is working with the write-in screen. In order to design the screen, a table is being used to establish the coordinates in which a letter will appear. Javier is working with the screens for voting. These screens include language selection, integral or mixed voting selection as well as write in option selection. Angel is working with the encryption and decryption of the information stored in the database. Sylvia is working with the keypad for navigation. Yesterday Sylvia and Javier tested the keypad to look at the output voltage from each of the pressed keys. The keypad regulates the input voltage to have an output voltage of 3V. Therefore, there is no need to have a voltage regulator. Sylvia, Javier and Laura are working with dependent modules from one another; therefore before start working the design was discussed.
