| Nov 29 at 11:40 | comment | added | Motine | hey @Antonio51, wow there are a lot of ideas. Thanks! Since I am not a professional, can you "unpack" the things a little for me? - I can add a capacitor. Can you share why this is might solve the problem? - Mmm, so I should not use the power source of the Arduino? Would a powerbank do? (since batteries tend to be more stable?) - What do you mean with "also"? Decouple the Uno and something else too? - What does C6 refer to (googling did not yield results)? | |
| Nov 29 at 9:26 | comment | added | Antonio51 | HX711 is "ratiometric". Try a capacitor (100 nF) directly on pins E+ and E- of the board. E+ and E- are "outputs", I think. So can't be wired to Uno power supply. Decouple also, if needed, VCC and GND on the board. C6 should do it, but perhaps not enough (long wiring). | |
