Product description 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. 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 Package Includes: 5 x KY-032 Infrared Obstacle Avoidance Sensor Module
