Sorry for creating this question but I spend so much time with the (re)search.
I've been searching for the solution for the FADE effect for ordinary 5m LED strip. (white)
When hitting the light switch on - Led strip fades in (on). (during like 0,1sec)
When hitting the light switch off - Led strip fades out (off). (during like 0,1sec)
No other effects.
I've watched ton of videos about FADE (LED).
Solution of simple circuits (non-arduino) and arduino controlled.
Can't found what I'm looking for.
Please help me with this.
There are lot of results but they are usually:
*- examples of fade in/out effect with 1-5 LED diodes *
*- controlling RGB Led strips *
*- flickering or repeating fades (light shows) *
*- project disputed by comments under the project *
*- manually controlled dimmers *
The LED strip is ordinary 5m 12V white strip. Takes 30W (2.5A).
How would you "solve" the fade on/off for the strip.
(I consider both non-arduino solutions and arduino control solution)
(there might be more solutions unknown to me. Or solutions better to avoid.)
One way or another I am asking for help with this.
Very appreciate it. Thank you.
You will need a driver, the Arduino is not capable of supplying that amount of current. You can find an example that is close then modify the code to suit your purpose.
I would like to choose this solution. (I liked it even before)
But will I need also a capacitor? (I think I will and a big one. Can you advice me what capacity to choose?)
I needed no cap with an early 3 color strip but a bypass cap on the external power supply might be good. Remember that the controller only switches the leds on and off faster than you can see to appear dim.
I went and bought WS2811 RGB led strings/tree lights. You give them Amps of 5V and 1 pin can set every led of 50 or 100+ any 24-bit color you want faster than you can see, the FastLed Library makes it easy.
