Infrared remote control module
Infrared controller (in other TkkrLab Arduino Set)
This is a new ultra-thin 38K universal infrared remote control, using the NEC encoding format, mainly for cars Containing MP3, foot bath, lighting design equipped, digital photo frame, microcontroller development board learning board and other occasions. Because it is based on non-Line remote control, so people seem easy to use, effective, and now more and more wide application field, then for This product of our company that we will make the following introduction.
Specifications
Infrared remote control distance: more than 8 meters
Launch tube infrared wavelength: 940Nm
Crystal frequency: 455KHZ crystal
Carrier frequency: 38KHZ
Encoding: encoding format for the NEC
Size: 86 * 40 * 6mm
Power: CR2025/1600mAH
Use
Remember that the remote control and the ir receiver is a set, it has to decode the code and will display a hex code.

Wiring the pi with the module
left pin (GND) to pin 6 (GND)
Center pin (VCC) to pin 1 (3,3V)
Right pin (DATA) to pin 12 (GPIO 18)
Setting up Raspbian
Before running any code, install LIRC with sudo apt-get install lirc and the follow the prerequisites below
edit /etc/modules and add the lines below:
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=17
edit /etc/lirc/hardware.conf and modify to add the correct values as below:
DRIVER="default"
DEVICE="/dev/lirc0"
MODULES="lirc_rpi"
edit /boot/config.txt and edit the dtoverlay value like this:
dtoverlay=lirc-rpi,gpio_in_pin=18,gpio_out_pin=17,gpio_in_pull=up
reboot your pi
after reboot:
stop lirc daemon: sudo /etc/init.d/lirc stop
test your ir receiver by running: mode2 -d /dev/lirc0 then by pushing any key on your remote to see if something happens (random numbers)
your ir receiver is working !
