ขาย IR Infrared Obstacle Avoidance Sensor Module for Arduino Smart Car Robot ราคาที่ดีที่สุด

Pin, Control Indicator Description Vcc 3.3 to 5 Vdc Supply Input Gnd Ground Input Out Output that goes low when obstacle is in range Power LED Illuminates when power is applied Obstacle LED Illuminates when obstacle is detected Distance Adjust Adjust detection distance. CCW decreases distance. CW increases distance. IR Emitter Infrared emitter LED IR Receiver Infrared receiver that receives signal transmitted by Infrared emitter. // IR Obstacle Collision Detection Module // Henry's Bench int LED = 13; // Use the onboard Uno LED int isObstaclePin = 7; // This is our input pin int isObstacle = HIGH; // HIGH MEANS NO OBSTACLE void setup() { pinMode(LED, OUTPUT); pinMode(isObstaclePin, INPUT); Serial.begin(9600); } void loop() { isObstacle = digitalRead(isObstaclePin); if (isObstacle == LOW) { Serial.println("OBSTACLE!!, OBSTACLE!!"); digitalWrite(LED, HIGH); } else { Serial.println("clear"); digitalWrite(LED, LOW); } delay(200); }
