4N35 DIP

Description

4N35 DIP

Tutorial: How to Use 4N35 DIP

The 4N35 DIP is an optocoupler isolator ideal for protecting electronic circuits from electrical interference. Useful for beginners and intermediates working with low and high voltage circuits.

What you need

• 4N35 DIP
• Arduino or electronic circuit
• 1kΩ resistor
• Power supply

Steps

1. 1. Check the datasheet for the specifications of the 4N35.
2. 2. Connect the power supply to the 4N35.
3. 3. Connect the resistor to the input pin of the 4N35.
4. 4. Connect the output pin of the 4N35 to an LED.
5. 5. Connect the third pin of the 4N35 to ground.
6. 6. Verify the connection with a multimeter.
7. 7. Load a simple sketch onto the Arduino.
8. 8. Check if the LED lights up when a digital signal is sent.

Example code

```void setup() {  pinMode(2, OUTPUT);}void loop() {  digitalWrite(2, HIGH);  delay(1000);  digitalWrite(2, LOW);  delay(1000);}```
