In compliance with the tutorial, an electronic scale can be produced by boards, slot connection and wiring.
It also has a membrane keypad, a weighing sensor, a DS3231 module and an LCD 1602 display module Furthermore, the detailed projects will guide you to learn the working principle of sensors and modules.
If interested in STEM and code programming, you can customize your own scale by altering code and adding extra modules. That sounds entertaining, right? Let’s get started!
