Building a Scale from Scratch

Course: ME102

Year: 2020

Purpose: Learn to build a scale using knowledge from Statics class

This scale was built by learning a variety of skills including:

• Soldering

• Coding Arduino IDE

• Producing "noise-free-resolution code"

• Using potentiometers

• Applying wheatstone bridges

• Load cell building

Process:

First, pins were soldered to the Arduino mini board and HX711 board. On the breadboard, the boards were attached to a potentiometer. The set up was then attached to a load cell. Arduino code was optimized to be noise-free and calibrated.
