I have never built anything Arduino related stuff. I barely know how electronics work but i can solder pretty well and knows the basics.
I have been wanting to build MIDI controller using arduino for quiet awhile now. So i decided to build one using Arduino Leonardo. Which has USB-HID.
Now. i want to have 4 buttons for banks, 16 buttons for inputs. So i got two 8x1 multiplexers and connected them to the Arduino like this.
I first connected them like this. and after i saw the second image i connected the rest of multiplexer pins to ground.
This image is for 1 multiplexer and for analog signals. mine is digital.
I don't know if it will work or not. any advices? tips?
I need help
