Electronic scales are a familiar sight in daily life, primarily used for weighing. However, professional-grade scales on the market often offer advanced functions and higher precision. But what if enthusiasts wanted to build their own electronic scale using the skills they’ve learned? The good news is, you absolutely can! Creating an open-source electronic scale is surprisingly simple. All you need is a weighing module, an HX711 AD chip designed for weight measurement, and an Arduino with the appropriate library. With these components, building your own scale becomes a straightforward and rewarding project!
