Gikfun Infrared Diode Led IR Emission and Receiver for Arduino (Pack of 10 Pairs) EK8460

everybody talks about Bluetooth and Wi-Fi but one heavily used technology is often forgotten infrared today we will remember this technology and bring it to the today's world of microcontrollers like the ESP 32 and the esp8266 and 2 technologies like MQTT and node-red and as usual we will take a little into the basics create see youtubers here is the guy with the Swiss accent with a new episode around sensors and microcontrollers today we will use infrared rays to detect objects and find a way to make the detector immune against interference from daylight we will use standard photo diodes as well as IR receivers to detect signals and see the difference then we will use infrared instead of Laura or Wi-Fi to transport information over the air we will enable an Arduino Uno to receive learn and send infrared codes we will port the infrared or IR library to the ESP 32 and implement MQTT fina
