Working With Force Sensor Using Arduino Mega 2560

Introduction

• In this article, I have explained about working with Force Sensor using Arduino Mega 2560.
• It explains about sensor with the pressure of the mode.

Parts Of List

• Arduino Mega 2560
• Force Sensor
• LED
• Hook Up wires
• Bread Board

Force Sensor

• This is a force sensitive resistor with a round, 0.5" diameter, sensing area.
• This FSR will vary its resistance depending on how much pressure is being applied to the sensing area.

Connection

 

Step 1: >Connection from Sensor to Arduino Mega 2560.

• Connect the sensor first pin to the Analog pin of Ao to the board
• Connect the sensor second pin to the 5v of the board.

Step 2: Connection from LED to Arduino Mega 2560.

• Connect the positive pin to the digital pin of 03 to the board.
• Connect the negative pin to the Gnd of the board.

Programming

int ledpin = 3;
int sensorPin = A1;
int value;
void setup()
{
    pinMode(ledpin, OUTPUT);
    Serial.begin(9600); // Baud Rate
}
void loop()
{
    value = analogRead(sensorPin);
    Serial.println(Force: );
    value = map(value, 0, 1023, 0, 255);
    Map value 0 - 1023 to 0 - 255(PWM)
    analogWrite(ledpin, value);
    delay(100);
}

Explanation

• This explains about the pressure of the sensor mode.
• It can have a high range in the force that we have given to the sensor.
