Advanced LED candle on ESP32 -- 2

Hi I would like to build a LED candle, like these : [login to view URL] interesting from 1:10 The flames of my candles should be 4 times as large and they should be a lot brighter. Also the LEDs should change brightness, SOFTLY flickering. The flame is going to be moved by 4 solenoids. The flame has a neodym magnet on the bottom. I did do some trials on programming, but since I am not a programmer I didn't get a satisfying result. There is a lot of candle software out there but I only found one, which had a pleasing light effect. I tried to multitask it with freertos, but failed. I attached this file, well what I tried. The code for one LED is from line 75 - 144. It dims between the old and the new (random generated ) brightness value. This is the original to it : [login to view URL] other interesting non-blocking code : [login to view URL] it works nicely, especially the " breathe " mode, but there is not much possibility to change the values, once it is started. Also the breathe always starts from 0. Maybe there is some tweaking possible in the . h and .cpp files. What the program has to do : Flicker ( softly ) LED channels independently . Move the candle flame with the 4 solenoids. Randomly with random current. The solenoids should be on pwm, to adjust for mechanic differences. The actual movement could be done by just the length of an impulse. There should be room for choreography, since the flame reacts differently to the impulses, once it is moving. All these " effects " have to work independently. IMHO all delay() functions will not work, or give it a predictability, which is not desired. Besides from setting some values / variables, some values should be adjustable by remote control. as there are : Overall brightness Frequency and amplitude of the candle motion also the dominant direction Frequency and amplitude of the candle light, the 2 big leds with lenses Frequency and amplitude of the ambient ( candle body ) light, the 12 small leds around the flame. There would be 6 channels with 2 leds ON / OFF switch The remote can be extremely simple, maybe use Blynk or ESP32-Mesh as a base. Or any other wifi/ wlan app or a simple web browser In the final version there will 150 candles, so any remote with mesh option would be preferred. I did some very easy wiring layout for it, with a MIC2981 for the ambient light ( same voltage on all outputs ) and a ULN2003A different voltage for flame leds and the coils. For the initial setup of the values and variables it would be great, if we could use a display with sliders, I bought a Nextion NX4832K035 display for that, but maybe changing the values in the code would do as well, just takes a lot of time compiling and uploading. Thanks
