Tutorial: How to use 2N7000

The 2N7000 is an N-channel MOSFET transistor that can be used for controlling electronic circuits. Useful for beginners and intermediates.

What you need

• 2N7000
• Arduino
• Resistance (1kΩ)
• Power supply (5V)

Steps

1. 1. Installation: Attach the 2N7000 to the printed circuit board (PCB) or breadboard.
2. 2. Connection: Connect the power supply (5V) to pin 2 of the 2N7000.
3. 3. Connection: Connect pin 3 of the 2N7000 to the Arduino output pin.
4. 4. Connection: Connect pin 1 of the 2N7000 to ground.
5. 5. Connection: Connect a 1kΩ resistor between pin 2 and ground.
6. 6. Sketch: Upload the following code to the Arduino.
7. 7. Test: Power on the circuit and check if the transistor works correctly.
8. 8. Verification: Check if the circuit works as expected.

Example code

const int mosfetPin = 9;
void setup() {
  pinMode(mosfetPin, OUTPUT);
}
void loop() {
  digitalWrite(mosfetPin, HIGH);
  delay(5000);
  digitalWrite(mosfetPin, LOW);
  delay(5000);
}

Mini project

Create a simple on/off circuit for an LED using the 2N7000 as a switch.

Common mistakes

• Connect the power supply directly to pin 3 of the 2N7000 without a resistor.
• Do not properly verify if the transistor works.
• Use a power supply different from 5V.
• Do not properly follow the polarity of the connections.

Recommended accessories

• LED
• LED resistor (220Ω)
• Breadboard
• Breadboard wires

Frequently asked questions

How can I verify if the transistor works correctly?
Measure the voltage between pin 3 and ground with a multimeter.

Can I use a different voltage than 5V?
Check the datasheet: the 2N7000 supports supply voltages ranging from 4V to 20V.

What are the risks of misuse?
It could damage the transistor or the Arduino.
