2D2 IRF520 MOSFET Driver Module

Description

This little module (HCMODU0083) is a breakout board for the IFR520 MOSFET transistor. The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Its main purpose is to provide a low cost way to drive a DC motor for robotics applications, but the module can be used to control most high current DC loads. Screw terminals are provided to interface to your load and external power source. An LED indicator provides a visual indication of when your load is being switched.

Interfacing IRF520 MOSFET Driver Module with Arduino

Step 1: Circuit

The following circuit shows how you should connect Arduino to IRF520 sensor. Connect wires accordingly.

Step 2: Code

Upload the following code to Arduino.

#define PWM 3
int pot;
int out;

void setup() {
  Serial.begin(9600);
  pinMode(PWM,OUTPUT);
 
}
 
 
void loop() {
  pot=analogRead(A0);
  out=map(pot,0,1023,0,255);
  analogWrite(PWM,out);
}

In this code, by rotating the potentiometer, the value of PWM pin 3 changes from 0 to 5. The voltage of the motor also changes from 0 to 9.
It can be seen that by turning the potentiometer, the motor speed can be controlled.
