So at this stage of my project I have everything on a breadboard connected with jumpers. All the buttons each have one of their terminals going to the ground rail which is connected to one of the teensy 4.1's ground pins, and the other terminal is connected directly to one of the teensy's pins. then I have the oled display all directly connected to the teensy, (using up another ground pin) and lastly I have the audio board rev D connected directly to the teensy, using up the last ground pin. (again, all connected via jumpers) now, I used to have the audio board's ground going to the ground rail on the breadboard, but it had a lot of noise there so I now have it directly connected to the teensy. This has reduced a lot of the noise, but there's still a fair amount of white noise blaring over the wav file that is playing. Could this be because of all the jumper wires being in close proximity to each other? (the breadboard looks a bit like a mess of wires) The final project is all going to be soldered onto a perfboard and everything is going to be connected using single core 1/06mm wire, which is much better than jumper wire, right? I know the best decision would be to have the audio board directly soldered onto the teensy board itself, but when I got the audio board I was way too eager and immediately soldered some headers onto it. Now if I must, I shall go through the process of desoldering all these headers... but I'm sure you can see why I want to find an alternative, eheh. Any help would be much appreciated!
