This post / video follows on from Part 1 of the Tactile Switch version of my Hex Keypad project, where I assembled my first Keypad.
For Part 2, it’s now time for some testing!
For testing, I use Arduino to implement a USB Keypad. Although the intended use of the Hex Keypad is for Retro Computing projects, Arduino allows quick, easy and visible testing of the 4×4 Matrix Keypad’s operation.
So, please join me on this Part 2 of my Hexadecimal Keypad journey, where I first demonstrate my original 70’s Hex Keypad operation with a simple Arduino sketch, and then use the sketch to test my new Tactile Switch version Hexadecimal Keypad.
If you’d like a Hexadecimal Keypad for your own retro computing projects, you’ll find the Kitset on my Tindie store:
