Review on 📡 KOOBOOK 2 Pcs HX1838 NEC Infrared IR Wireless Remote Control Sensor Module + IR Receiver Module DIY Kit for Arduino by Nick Narvasa

I received two remote controls, two modules and two sensors as described. With a sensor and module connected to an Arduino Uno, I was able to read the IR codes from my many remote controls, allowing me to create a custom remote using the Arduino to control all my audio/video stuff. Works great with "IR Remote Library by Ken Shirriff" on Arduino. It's very easy to create a project to use the included remote control to send codes to control multiple relays using an Arduino and a relay shield. Very happy with this purchase.
