Can I use a Raspberry Pi to control lights?
To control lights at home, smart lights like Philips Hue are required. With a Raspberry Pi, the Python programming language allows you to connect to the lights API, and manage them with a script. This is what we’ll do today!
Can I run a 24V LED on 12V?
If you’re trying to go the other way and connect a 12V power supply to operate 24V LED strips, unfortunately, you are out of luck. The reason is that a 24V LED strip has 6 LEDs in series per group, and there is no way to “split” this to match a 12V power source.
Where is the LED strip on a Raspberry Pi?
The WS2801 RGB LED strip has 2 data pins (here: CK and SI) as well as the 5V connector and GND. If you are aware of which cable leads to which connection, we can connect it. The Raspberry Pi should be switched off and the switching power supply should not be connected to the socket. The cables are connected as follows:
Is the WS2812 RGB LED strip compatible with Raspberry Pi?
After using the latter in a previous tutorial and using it in our Ambilight, this tutorial is about using the Raspberry Pi WS2812 RGB LED Strip. The models WS2812B and WS2811 are also compatible and can be addressed with this guide. It must be said that one should not be fooled by the “smaller” model number of the WS2801.
What kind of power cable does Raspberry Pi use?
Overall, only two cables run from the Raspberry Pi to the WS2812 LED Strip: GPIO 18 (to DIN) and GND to COM of the PSU and GND of the strip. Depending on the length of the LED strip, the external power connection should be installed in several places.
Which is the neutral conductor on Raspberry Pi?
The black or brown inner cable comes to the outer conductor “L”. The blue inner cable comes to the neutral conductor “N”. The green-yellow inner cable is connected to the protective conductor “PE” or earthing symbol. The voltage should be about 5V.
