If (potPWMValue < 102)// below PWM value 102(Vgs=2v) use PWM value 0 to avoid rough run Int potPWMValue = map(potAnValue, 0, 1023, 0, 255) // mapping to get 0 to 255
Int potAnValue = analogRead(pot) // read the input pin declare pin 3 and A0 to be an output and input respectively: Int pot = A0 // potentiometer is connected to analog pin 0 Int motorPin = 3 // the pin that the motor is attached to Upload the code given below to your Arduino baord:ĭC Motor speed control using FQP30N06L with Arduino and potentiometer.To know more about Arduino PWM frequency change, read this article. Gate of the Mosfet is connected to the Digital PWM pin 3 of the Arduino UNO here, you can connect it to any other PWM pin according to the Load PWM frequency OR switching frequency requirements.Load can be a Motor, a lamp, solenoid etc.Connect the Arduino with the Mosfet using the required components as shown in the circuit diagram above.To use FQP30N06L with Arduino follow these steps: FQP30N06L Mosfet with Arduino Circuit Diagram
