Introduction

Have you ever wanted to know the weight of something? How about knowing the change in weight over time? Do you want your project to sense the presence of something by measuring strain or a load on some surface? If so, you’re in the right place. This tutorial is here to help you get started in the world of load cells and their variants.

Before jumping into load cells and all of their awesomeness, we suggest you familiarize yourself with some basic concepts if you haven’t already:

Voltage, Current, Resistance, and Ohm's Law

Learn about Ohm's Law, one of the most fundamental equations in all electrical engineering.

Voltage Dividers

Turn a large voltage into a smaller one with voltage dividers.

Resistors

A tutorial on all things resistors. What is a resistor, how do they behave in parallel/series, decoding the resistor color codes, and resistor applications.

Series and Parallel Circuits
