This module allows for sensing of solid objects within a fixed range (adjustable with on-board potentiometer). Ideal for robotic applications. This is a simple example of how to use the Hobby Components obstacle avoidance sensor module (HCMODU0006). It is a very simple module that requires only one DIO pin (defined as an input) to operate. When the sensor detects a reflective object in close proximity it will pull a connected DIO pin LOW. A non reflective or no object in close proximity will cause the DIO pin to go high.
PIN 1: GND
PIN 2: +5V
PIN 3: DATA OUT
PIN 4: ENABLE (NOT CONNECTED)
