Automatic Liquid Filling Machine

Aug 2026
ArduinoElectronicsLoadCellRelays

Diving into hardware automation by building an automatic liquid filling machine. Uses an Arduino to read weight data from an HX711 load cell module and triggers a 12V peristaltic pump via a relay module once target weight threshold is reached.
