The pins need to be remaped for the extension board, where (sensor: board) - following the example code:
- GND: G
- +: V
- out: D15
- EN: D16
Pins:
- GND – should be connected to ground
-
- – should be connected to 5V power supply
- out – obstacle signal
- EN – no use found
Theoretically this is made for tracking lines, though, through tests, it detects any close object (obstacle detection).
Calibrate it through the potentiometer. It may make a great difference on results.
Works best in the dark.
