Hi,
Am working on a device that measures the dropped weight but I had that problem that openScale suddenly stops reading weight and give me “nan” or random numbers…I had to replace three OpenScales till now
my system consists of 12V power supply, three (100Kg) Loadcells summed by junction box ,Arduino Mega, Three Relays, and openScale… I tried to protect the electronic by flyback diodes but that didn’t help.
The Scenario of damage:
everything would works perfectly till it starts with a sudden freeze in Arduino Serial that even if I reset the arduino manually wont go out So I have to cut the power for like 5 secs and reopen it …at that moment the OpenScale starts to give false values and no hope to reuse it…
what the possibilities for that issue and what can I do to prevent it
