i am currently working on this project.
In short: Open-Source Project for receiving and sending infrared signals (which i will later controll with pimatic via the Open-Remote API)
I understand the schematics and already sticked the parts together. Now I am able to receive the infrared signals of my YAMAHA remote and save them to send them out later via the two leds.
My problem: I cant send signals. I checked the wiring like 100 times and don’t think that i did something wrong. I now believe i bought the wrong parts, as i wasnt able to get exact the same LEDs and the same transistor as the guy in the tutorial was using.
It would be really awesome if someone of you -who knows what he is doing- can say my LEDs and my transistor is ok for this.
These are my parts connected:
And here you can see which colors are connected to which GPIO pins of the raspberry: Red: 5V, Blue: GND, White: GND(to receiver), Yellow: GPIO22
I hope the given information are enough for you to find my mistake because i am really looking forward to integrate my TV and my AV-Receiver into pimatic.
Of course i will write a tutorial on this if im having success!
Thanks a lot
