In this article, we connect a KY-010 light barrier module to our Microbit – we will use Makecode and show the JavaScript and Python output as well
The KY-010 light barrier module / photo interrupter module is a 3-pin module that brings its signal pin HIGH when an object blocks light from traveling between its emitter and sensor.
