This is very close, allowing for tolerances, to the 27k resistor you are also using meaning that it could be difficult to distinguish between a single button press and at least some combinations of multiple button presses. | |

You could probably rewrite as only doing greater-than tests. For example, >= 227, then if it fails that, >= 212 and so on. Testing the other limit seems redundant. | |
| Jul 29, 2023 at 22:59 | comment | added | boop | @NickGammon I just inserted different resistors to test each of them one by one. That was easier than setting up 6 buttons and was good enough. Just needed to know if it works in general | |
