Based on PCA9685 and ESP8266 it is configurable for 2 to 64 PWM output channels.
16 outputs per PCA9685, for 64 outputs you need 4 X PCA9685.

It consists of 2 dimmer channels, 3 staircase timer channels and one light switch:

the first dimmer set the level of the outputs for when they are on between 50% and 100%.
the second dimmer set the level of the outputs for when they are off between 0% and 50%.

three staircase timer channels:
the first to turn on in sequence from the first output to the last and turns off in sequence from the first to the last."also with button 1"
the second to turn on in sequence from the last output to the first and turn off in sequence from the last to the first."also with button 2"
the third to turn on in sequence from the output set as center to the first / last and turn off in sequence from the output set as center to the first / last."also with button 3"

One light switch channel to turn all the channels On / Off at the same time.
allows to leave On."also with double click on any button"

For testing you can connect Led diodes directly to the outputs and GND.
Gpio4 "D2" = SDA -- PCA9685
Gpio5 "D1" = SCL -- PCA9685
Gpio2 "D4" = LED_PIN
Gpio0 "D3" = button_0
Gpio14 "D5" = button_1
Gpio12 "D6" = button_3

ESP Buildin Led:
winking 0.5 seconds = not connected / connecting.
on = WiFiConfig.
off = connected / Ok.

button 1:
click = toggle On / Off from 0 to XX "climb stairs".
double click = togle all On / OFF.
hold 10 seconds = WiFiConfig.

button 2:
click = toggle On / Off from XX to 0 "go down stairs".
double click = togle all On / OFF.

button 3:
click = toggle On / Off from center to 0/XX.
double click = togle all On / OFF.


in WiFiConfig are some additional parameters:

"Fade Time for each Step".
this is the time it takes to turn on each output in milliseconds, 500 is a good value to start with.
500 * 16 = 8 seconds.

"Number of Step".
number of outputs up to a maximum of 64 (4 x PCA9685).

"Center Step".
central channel "button 3".

To connect the led strip, I have to use something else, can it be directly connected to the PCA9685

you can't connect directly to the PCA9685.
you have to use a mosfet and a resistor as seen in the image connected to channel 0.
1 mosfet and 1 resistor for each output.

1 mosfet and 1 resistor for each output.
And what kind of mosfet must it be?

NPN type mosfet for example AOD4184A
