How do you control led 5050?
To control the brightness, the normal way is to use PWM – switch on the required power for a short period of time, switch it off. Do this at a high frequency. By altering the time it is on/off, you can control the brightness.
Can you cut individually addressable LED strip?
This kind of strips are very flexible and can be cut to any length you want. As you can see, the strip is divided into segments, and each segment contains one RGB LED. You can adjust its size by cutting the strip with a scissors in the right place (the proper places to cut the strip are marked).

How does the fastled library work with LEDs?
If you have ever used LEDs before, the way that you light the LEDs on an LED strip may seem counterintuitive. With the FastLED library, you are not determining which LEDs to light, but instead, you are setting colors to the LEDs and then lighting all of the LEDs on the strip at once by using the function FastLED.show ().
How to use fastled with multiple LED strips?
Now FastLED has a lot of build in function which I would like to use, as for example a function which lights up one led strip at once in a certain color: But I’m not sure how to pass the first argument to the function when having multiple led strips instead of just one (as in my case). Can anyone help me with this? Thanks! PS:
How to change the brightness of LEDs with fastled?
FastLED.setBrightness (BRIGHTNESS ); Later on I have a made a small function which I use a button press to conrol leds but I want the brightness to change to max 255. But I’m not sure how to do this….Or where to look……
How to control the color of the LEDs?
The colors of the LEDs in your sketch are set in this loop: You loop over all LEDs and set them to a specific color and brightness. The changes will be send to the LEDs, when you call FastLED.show () afterwards. There is nobody, that prevents you from setting a different color for each LED or to only chnage the value for some of the LEDs.
