Introduction
- In this article, I have explained about working with Force Sensor using Arduino Mega 2560.
- It explains about sensor with 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 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);
- }
- 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 the high range in the force what we have given to the sensor.
