Hat niemensch bemerkt, dass der #Spannungsteiler am #LM358 falsch war ... musste umlöten ... jetzt ist richtig und funktioniert mit vorgegebenen Spannungen.
Morgen dann den #Solar-Strom einkoppeln.

Three potentiometers control the duty cycle for pulse width modulation of the three colour channels of an RGB LED strip (non-addressable). The PWM signal is generated by #opamps (#LM358) configured as an oscillator and 3 comparators. An NPN transistor sinks the current for each of the LED colours.

Pulsating PWM using two #LM358 dual #opamps configured as a fast oscillator, a slow oscillator, and a comparator whose output is the source of one LED and the sink of another LED
