Highschool laptop engineering instructor (*8*) stored shedding observe of I/O pins on his home-built synth, so he made a customized (*2*)plug and play addressable MUX formulation to unravel the issue. [Andy]’s synth is according to the Teensy microcontroller, and he used to be already the use of CMOS analog 8:(*17*) multiplexer chips (CD4051) to provide him extra I/O pins. However I/O pin growth signifies that now there are extra I/O pins to put out of your mind. (*13*)Did I hook up that pitch potentiometer on U3 pin 13 or used to be it U10 pin 2?
thorough documentation that [Andy] has ready, and tell us when you’ve got ever designed your individual plug and play means for a challenge within the feedback beneath.
