Arduino IDE Slider ESP

Hallo zusammen,

ich versuche gerade eine RGBW Steuerung per ESP mit der Arduino IDE.
Ich bekomme den Wert ausgelesen "NewRvalue".
Ich habe das etwas zusammengestückelt aus Internetbeispielen.

Was ich noch möchte ist:

1.diesen Wert in den VALUE Wert des Sliders einzufügen damit dieser 
nicht immer in die Mitte zurück springt. Ich habe schon viel versucht 
leider ohne Erfolg

2. Wie kann ich diesen Wert im EEPROM speichern damit er nach dem 
Nuestart noch zur verfügung steht?

Danke :-)

So das mit dem Wert im Slider übernehmen klappt jetzt.
Anbei mal der Code.

Leider klappt das mit dem speichern im EEPROM nicht.

Hätte da jemand einen Vorschlag bzw. könnte das mal implementieren?

Es reicht mir wenn der Wert von R sagen wir an Adresse 0 geschrieben 
wird und G an 1 / B an 2 und W an 3

Ich habe es nach diesen Beispielen Versucht leider ohne Erfolg

Hallo,

habe mir nicht alles angeschaut, aber ich sehe keine EEPROM Aufrufe...
Weder
EEPROM.begin(512); noch  EEPROM.write(addr, val); und kein 
EEPROM.commit();

Eigentlich ist das Handling doch unproblematisch und das Beispiel 
verständlich?

Gruß aus Berlin
Michael
