Build an Arduino EEPROM programmer. The code in /multiplexed-display is for programming an EEPROM to be used to decode 8-bit values and drive a 4-digit 7-segment display. Check out this video for more: Build an 8-bit decimal display for our 8-bit computer.
In this video, we'll use an Arduino Nano to make programming EEPROMs (e.g., 28C16) much easier. For more info on these EEPROMs, check out the previous video:...
In these videos, I talk about how VGA signals work and build a circuit that provides the correct timing of sync signals so that a monitor recognizes the signal and displays an image stored on an EEPROM.
