    • HW-488 infrared sensor not detecting properly

      I’m testing the HW-488 IR obstacle avoidance sensor with my Arduino, but the readings are weird. Sometimes it doesn’t detect anything, even if I put an object really close. Do I need to do something with the EN pin, or should it just work with VCC, GND, and OUT?
