my serial connection prints rubbish, but it systematic, so it's not just random as you see on image 1, any help would be appreciated
other info:
the first image of the serial monitor of COM6 is my own serial connection, image nr. 2 is the serial monitor of COM4 which already uses the onboard serial to USB the last image shows how I made my own serial connection
the 2 black cables are providing around 4 volts, I know these are not necessary cause the USB already provides 5 volts and ground
and oh ye, normally the USB on the last image would be connected to my pc ofc
