IR Remote Control on RaspberryPi

Rough Draft

For a long time I’ve wanted to use my Pi as as WiFi controlled IR Remote.  e.g Connect to it vi a WiFi and have it beam IR codes to any device that uses them.

With PiZero this becomes cheap and affordable to do.

i looked around and found that LIRC is the software needed to do this so I installed it mainly using this blog.

However, I seemed to find that the instructions were slightly unclear to me so let me jsut emphasse/add the stuff I did to get it going

Note – I cheated at first by just connecting transmitting diode direct to PiZero – you should really use a little transistor cct but since PiZero are £4 – i decided to risk it YMMV

Using Pin18(GPIO 23) for the receiver and Pin20(GPIO 24) for the transmitting diode.

Make sure /boot/config.txt has this line in it

dtoverlay=lirc-rpi,gpio_in_pin=23,gpio_out_pin=24

If all goes well and you can record your remote then all thats needed to use it is to run

sudo irsend SEND_ONCE name_of_remote key

where name_of_remote is the one in your /etc/lirc/lircd.conf file and key is the code you want to send

To send these using ScratchGPIO then you can use

broadcast join (run sudo irsend SEND_ONCE name_of_remote ) (key)

and just change the value of key

IMPORTANT: make sure there is a space after name_of_remote

I’ve managed to put together an lircd.conf file for these GU10 type rgb  bulb
