DIY Kitchen Scale
Weigh up to 49.05 kg∙m/s^2 with Arduino
The starting point for this article was a project posted on Elektor Labs describing the construction of a kitchen scale from an ATmega328 microcontroller, a load cell, a load cell interface board, an LCD, and some software. A bit of cutting and drilling of wood and metal was required to transform it all into a useable weighing scale.
