but since I have to run through the 74HC14 on this design I can't use that feature.
I'm just trying to follow this schematic
I'm not sure what the highlighted red line means exactly, sorry i'm rather new to all this so i'm sorry if that's a stupid question
Why? Just connect it to the Arduino
It shows a connection which is made when the "bright" button is pressed. Do you want that connection
The buttons trigger interrupts within my software
I see what you're saying, so in this case I'd need each button to have its own resistor to avoid that.
Now there is your problem We humans push the buttons. We humans are dead slow. Interrupts are for fast things. Aka, an interrupt is ALWAYS* the wrong choice for a button Correct, classic newbie brain fart Don't blame you, made them in the past as well. But it also shows to me you don't have a real clue why you do this. So my suggestion, drop the interrupt, just poll and debounce in software, saves you the hardware and easier to change PS Also, don't be evil and draw GND down. Only evil people drop it upwards * With the exception if it needs to wake the uC from sleep.
(i need you to trust me on this)
One thing I'm missing, the 100nF for the chip itself! Every chip wants a decoupling cap close by. Besides that and the evilness it should work.
Noting to do with the current caps, but something that applies for all chips, they want a 100nF ceramic cap over the power rail close by (aka, right next to the IC) so they have a clean power supply
Yeah, it's close on the schematic but he means physically close to the IC, as close as possible.
