Tutorial: How to Use the E18-D80NK Obstacle Avoidance Module

The E18-D80NK module allows Arduino projects to detect obstacles from 3 to 80 cm. Ideal for beginners.

What you need

• Arduino Uno
• USB Cable
• Power Supply

Steps

1. Connect VCC and GND to the module with the power supply.
2. Connect OUT of the module to a digital pin of Arduino.
3. Download the example code from the GitHub repository.
4. Compile and run the sketch on Arduino.
5. Check that the LED on the module lights up near an obstacle.

Example code

const int triggerPin = 2; const int echoPin = 3;

void setup() {
pinMode(triggerPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
}

void loop() {
digitalWrite(triggerPin, LOW);
delayMicroseconds(5);
digitalWrite(triggerPin, HIGH);
delayMicroseconds(10);
digitalWrite(triggerPin, LOW);
long duration = pulseIn(echoPin, HIGH);
calcDistance(duration);
}
