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

Great little sensors. I have only used 3 out of the 5, but these work fine, so assume all work. They also have two LEDs on them- one indicating it is on and the other indicating when it senses something.
