This video is about using the popular HC-SR04 Ultrasonic Sensor with an Arduino Uno to make distance measurements. You can use these measurements in many applications from robot object avoidance to parking sensors. • For more information see this post: https://www.nonscio.com/blog/q9gjkd7z... • See how this can be used to help a robot navigate autonomously! • How To: Build ScioBot 2.0 Vision Ultr... • #define echoPin 7 • #define trigPin 8 • long duration; • long distance; • void setup() { • // put your setup code here, to run once: • Serial.begin(9600); • pinMode(echoPin,INPUT); • pinMode(trigPin,OUTPUT); • } • void loop() { • // put your main code here, to run repeatedly: • digitalWrite(trigPin,LOW); • delayMicroseconds(2); • digitalWrite(trigPin,HIGH); • delayMicroseconds(10); • digitalWrite(trigPin,LOW); • duration = pulseIn(echoPin,HIGH); • distance = duration/58.2; • Serial.print(distance); • delay(50); • }
