Impressive. Before this i use to adopt Shift registers like 74595 and 74165 for driving LEDs and reading toggle switch/ push buttons respectively. Thanks
Amazing! I really need to see it in baremetal C with bit bangging for animations jajaja thanks for your videos! you are really helpfull for understanding better these concepts
thanks, I hope I learn enough C to do it, but I think my first implementation will be in Arduinos C++ variant. Will be intereisting to see when we hit an overhead roadblock for speed or memory usage.
Youre videos are very helpful, applying all the components that you've tackles which is great for ua beginners, also I'd like to learn more about programming/coding in arduino, if its okay please make more videos about programming/coding arduino, thank you so much in advanced
ELEMENT14, Try to make a video lesson explaining if you didn't use Diodes in the matrix what errors would happen when the scanning of the rows and columns which confuses the Scanning monitoring program to know which row or column the buttons are closed or open when the matrix doesn't use Diodes, this isn't called Ghosting but its called what? Ghosting buttons is only when you're holding down 2 or more buttons at the "same time" if a diodes is shorted or not using diodes.

I have tried those briefly years ago, also a good method ! I wonder if one could use shift registered with a chalieplexed matrix...hmm hmmm

thanks for the feedback, there is more coming!
Micah Elizabeth Scott came up with "Tucoplexing" to implement 4 LEDs and 4 buttons on just 3 wires.
oh I havent heard of tucoplexing yet, gotta google that! thanks!
Just been reading about that. Uses an RC circuit to detect switch presses.

Try to rephrase your question in clearer terms. As is i dont think I understand what you are asking.
