I have been trying to use a four-button PCB I had lying around in my house for one of my projects with a Raspberry Pi Pico. The problem is that I have never worked with such a layout that doesn't use a common ground for the buttons. This is the PCB: https://preview.redd.it/j4kcr5nxw2j91.j ... p&a982a5f9 And this is a schematic I drew of it: https://preview.redd.it/ivhh75o1x2j91.p ... p&06716cbd How can I interface with this PCB and know which button is being pressed in code? submitted by /u/Mauker_ [link] [comments] |
