## Strain Gauge Arduino Circuit Diagram

A strain gauge is a device that measures the amount of deformation in a material. It is made of a semiconductor material that changes its resistance when it is stretched or compressed. Strain gauges are used in a variety of applications, such as measuring the force applied to a structure, the pressure of a fluid, or the acceleration of a vehicle. In this tutorial, we will show you how to use a strain gauge with an Arduino to measure the weight of an object. We will use a simple circuit that consists of a strain gauge, a resistor, and an Arduino. The strain gauge will be connected to the Arduino analog input, and the Arduino will use the analogRead() function to read the voltage signal from the strain gauge. The voltage signal will be proportional to the amount of deformation of the strain gauge, which in turn will be proportional to the weight of the object. ### Materials * Arduino Uno or compatible * Breadboard * Jumper wires * Strain gauge (100 ohm) * 10 kΩ resistor * Weight (e.g., a book) ### Circuit Diagram The following diagram shows the circuit that we will be using in this tutorial.
