TIL117 Optocoupler DIP-6

Description

Tutorial: How to Use TIL117

The TIL117 optoisolator is ideal for protecting electronic circuits from electrical interference. It is useful for beginners and intermediates working with low and high voltage circuits.

What you need

• TIL117
• 1 kΩ Resistor
• Arduino
• Bench Power Supply

Steps

1. 1. Installation: Take the TIL117 and insert it into your Arduino board in DIP-6 position.
2. 2. Connection: Connected, connect pin 1 (emitter) to a pin on Arduino.
3. 3. Connect pin 4 (collector) to a pin on Arduino.
4. 4. Connect pin 3 (GND) to GND on Arduino.
5. 5. Connect pin 2 (VCC) to 5V on Arduino.
6. 6. Connect a 1 kΩ resistor between pin 5 (GND) and GND on Arduino.
7. 7. Connect a 1 kΩ resistor between pin 6 (VCC) and 5V on Arduino.
8. 8. Check the datasheet: Evaluate the maximum voltage and current specifications.

Example code

```
int emittente = 2;
int receptore = 3;

void setup() {
  pinMode(emittente, OUTPUT);
  pinMode(receptore, INPUT);
}

void loop() {
  digitalWrite(emittente, HIGH);
  delay(1000);
  digitalWrite(emittente, LOW);
  delay(1000);
  Serial.println(digitalRead(receptore));
}
```
