The arduino can also be operated very easily on and with the raspberry pi eg. The way it works for ir remotes is a code is sequenced through a series of on and off pulses through the led.

Driving An Ir Led Constant Current Source Or Not Arduino
It can for example also read analog sensors.
Raspberry pi ir diode. Now to drive ir remote code from raspberry pi there is additional hardware and a kernel overlay. Connect an led with a limiting resistor to raspberry pis gpio pins and you can control the diode using code written in your preferred scripting language. Raspberrypi sideprojects a few months ago i bought a raspberry pi and its been the best recent purchase i made by far.
Turn a raspberry pi into an ir remote control for your dslr tv or any other device with an ir port. You can remote control tv led strip dvd player or other ir remote control systems by the infrared remote function. Connected both a transmitter and a receiver to your raspberry pi and you could control all the ir devices in your home the ir led is like any other led can be hooked up directly to a gpio portbut will give better results if used with a pull down resistor this ir led can be used to control a tv with the emitter on an adruino and you can use the.
Install the infrared receiver diode in the raspberry pi gpio pins 2. Install and configure kernel module for the infrared receiver diode. Wire up an ir transmitter on raspberry pi.
Like all ir sensor it has three pins which are 5v gnd and out respectively. This s a ir transceiver expansion boardhat specially designed for raspberry pi 3 b 3b 2b b. The raspberry pi ir sensor interface can be converted into a proximity detector where the application will detect if the object is too close to the sensor.
Led4 is a 5mm 940 nm ir diode. Raspberry pi ir sensor interface. A true micro controller is eg.
How to turn your raspberry pi into an infrared remote control conceived on jun 9 2013 series. Install and configure linux infrared remote control software. The raspberry pi can also be used as a micro controller but it has a lot more functions because it runs an operating system.
Via usb or 433 mhz or 24 ghz radio. The ir sensor used in this project is shown above. Now that we have seen a little bit about the ir sensor module and its connections we will proceed with interfacing ir sensor with raspberry pi.
The above is covered in my other instructables. On board ir transmitter and receiver diode with 38khz working frequency are compatible with most ir remote controller. This instructable will not show.
The module is powered by the 5v pin from raspberry pi and the out pin is connected to gpio14 of raspberry pi. Use the infrared interface and remote control to do useful stuff.
