A load cell is a sensor designed to measure the weight of an object. Essentially, it is an aluminum bar containing 4 resistive strain gauges that are measured through a Wheatstone bridge to detect the weight of the object. In this project, using a small Microchip ATtiny1614 and a 5kg load cell, a 3D-printed scale…
In this project we see how to build a measuring wheel designed to be used over distances where rulers and tape measures are no longer practical. Even if it uses a rotary encoder with only 20 steps per revolution it can still provide good quality results by measuring, for example, the size of a room….
