The Crowtail- IR Receiver module uses the HS0038B which is miniaturized
receivers for infrared remote control systems and it is the standard IR
remote control receiver series, supporting all major transmission codes.
The IR detector has a demodulator inside that looks for modulated IR at
38 kHz, we can use our infrared remote control to control this module
well. The Infrared Receiver can receive signals well within 10 meters. If
more than 10 meters, the receiver may not get the signals.
Learn how IR receiver work and use it to control the LED with infrared remote control and
servo connected to micro:bit.
Learn how to detect the keys pressed by the infrared remote control.
