You can use this program to control all kinds of other functions in this case to switch on and off an led.

Force sensing resistors arduino. They are simple to use and low cost. A force resistive sensor changes its resistance based on the physical pressure or weight placed on it. Then the point between the fixed pulldown resistor and the variable fsr resistor is connected to the analog input of a microcontroller such as an arduino shown.

This video describes the operation of force sensing resistors and how to interface them to microcontrollers using an adc channel. The easiest way to measure a resistive sensor is to connect one end to power and the other to a pull down resistor to ground. Fsrs are basically a resistor that changes its resistive value in ohms w depending on how much its pressed.

We are using them in conjunction with an arduino to rotate a servo according to the amount of pressure. The resistance changes by applying pressure on it. This sensor is a variable resistor just like a photocell or flex sensor.

We only recommend this for advanced users that have adjusted their soldering iron for lower temperatures. Force sensor resistor pressure pad 100k resistor. In this tutorial you will learn how to use an fsr force sensitive resistor with arduino to fade an led.

An fsrforce sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing. A led pressure display and a toggle switch circuit is covered. The circuit for this arduino project is super easy as we only need the force sensing resistor and a 100k resistor.

In this example you will be using the fsr sensor as a toggle switch. It uses the following formula to calculate the output voltage. The force sensitive resistors from interlink are more sensitive compared to other flexible sensors.

Interfacing force sensitive resistor to arduino. There is a risk of damaging the sensor when soldering to the solder tabs. Vo vcc rrfsr.

Using a force sensing resistor fsr as a toggle switch. This sensor is a interlink model 402 fsr with 12 diameter sensing region. Fsrs are sensors that allow you to detect physical pressure squeezing and weight.

You will have to add a led with a resistor to the circuit which is shown in the diagram below. Below is the full list of equipment that you will need to complete this arduino pressure pad tutorial.
