Like 2 Months ago i started this "Project". I wanted to controll my LED Strip using my Pi. And this pi should host a Local webpage so i could control my led strip using any device in my Network. But unfortnetly im not very good at using Transistors, Cables, Grounds and stuff like that.


I have wired everything correctly i think (i checked it like 20 times), i rewired everthing 4 to 5 times, too and it still doesnt work how it should. So there is this software called PIGPIO, and basically, if i want to controll a certain pin on the pi i have to type "pigs p (the pin in this case 17) 255(for the intensitiy of the color 0 till 255). Thats what i know, and i also understood. But if iam typing this into the console, the led still has the same color i dont know how to fix it.

please help !111!!!!1!1 :D

    A LED strip is not normally controlled by sending PWM. Could you edit your question and include the model of LED strip you have bought. Also a clear photo or photos showing the wiring between the Pi and the LED strip will be useful. – joan Dec 10 '19 at 20:48

    working on it i just took some pictures, thanks for the fast response :) – NKFabian Dec 10 '19 at 20:49

    Add a link to the LED strip that you are using. – CoderMike Dec 10 '19 at 20:54

You appear to have got confused between the pin numbering of the GPIO connections on the Pi. There are several conventions including BCM (Broadcom pin number, commonly called "GPIO") and Physical (Number corresponding to the pin's physical location on the header).

The tutorial is using the BCM numbering however you have placed your connections in the Physical pin locations.

The following site should help you relocate your GPIO connections to the correct BCM locations.
