- Author: Noah Perez
- Description: I designed a Binary to Hexidecimal Decoder using a seven-segment LED display that takes inputs A - D and outputs a hexidecimal value between 1 - F.
- GitHub repository
- Open in 3D viewer
- View in Wokwi
- Clock: 0 Hz
How it works
The decoder takes a 4-bit binary input from the user and translates it to hexidecimal. This is shown via the seven segment display. I developed combinational logic, controlling each of the 7 segments and sectioned them for easy accessibility and troubleshooting. I color coded the truth table and K-maps to match that of the wires on the Wokwi project.
How to test
Toggle inputs A - D (1 - 4) to change the state of the seven segment display which displays a number 0 - 9 or a letter A - F.
External hardware
None.
