About 3 Pack KY-032 Smart Electronics Keyes 4pin IR
VCCA connects to 3.3V power supply VCCB connects to 5V power supply GND connects to power negative pole respectively, the two power supply should be common-grounded with each other When Ax has TTL 3.3V input, Bx will get TTL 5V output When Bx has TTL 5V input, Ax will get TTL 3.3V output NO direction control required Here we use the obstacle avoidance module and digital 13 interface with LED to build a simple circuit, making the obstacle avoidance warning light, accessing the avoidance sensor to digital 3 interface, when the obstacle avoidance sensor senses the signal, LED light, otherwise off. Program code: int Led=13;//define LED interface int buttonpin=3; //define obstacle avoidance interface int val;//define Digital variable val void setup() { pinMode(Led,OUTPUT);//define LED is output interface pinMode(buttonpin,INPUT);//define obstacle avoidance is output interface } void loop() { val=digitalRead(buttonpin);//reading the value from 3 digital interface to val if(val==HIGH)//when the obstacle avoidance sensor senses the signal, LED flash { digitalWrite(Led,HIGH); } else { digitalWrite(Led,LOW); } }
