Utilized various integrated circuits to design a 12 hour digital clock.

This project taught me how to use a seven-segment numerical display and various types of digital counters and gates to design a 12-hour digital clock. A seven-segment numerical display consist of 7 lines that will be used to display numbers depending on their inputs. The various types of digital counters and gates consist of a logical that runs inside of them to take in a certain input and outputs a desired output. To test theses devices, I experimented with them and understood what each part of the component does.

The 12-hour digital clock was created by using five components from our clock kit. The first component are the three two-digit 7 segment display common anode, which are used to display the digits. The second component are the six CD4543BE CMOS IC, which are the drivers for the seven segments. The third component are the two CD4510BE CMOS IC, which are binary coded decimals for setting and counting the clock for the hours. The forth component are the two CD4518BE CMOS IC, which are also binary coded decimals but for the minutes and seconds. The fifth component are the two CD4081BE CMOS IC, which consist of just AND gates. All five of these components are essential in creating the 12-hour digital clock by how they'll be logically connected.
