Hello All,
I'am new to this forum and new to microcontrollers and electronics.... I don't know wether this is the right place to post this topic.
I was following the above website in making a MIDI keyboard. But my keyboard has 128 keys in a 16X8 matrix . so I made a small change to the schematics shown in above website , by adding one more shift register and using 4 more unused pins in the Uno board.
I have two questions
-
is the schematic i have attached correct?
-
How should I modify the code to make the keyboard work?
please excuse my novice attempt at make a schematic, and my almost zero knowledge in code writing.
expecting your support ,
regards,
Alex.
