Hallo!
Falls die PWM Frequenzen nicht sehr hoch sind, sollte einfacher (Audio)Mixer mit eintellbaren Eingängen ausreichen z.B.:
Code:
VCC
+
|
.-.
| | Rc
| |
Rb '-' C2
___ |+[/
C1 +-|___|-+-[|-->
| | [\
\] | |/
+-------+-------+-------+-------+-------+-|]-+-----| T
| | | | | | /]+ |>
.-. .-. .-. .-. .-. .-. |
R| |<-+ R| |<-+ R| |<-+ R| |<-+ R| |<-+ R| |<-+ ===
| | | | | | | | | | | | | | | | | | GND
'-' | '-' | '-' | '-' | '-' | '-' |
| | | | | | | | | | | |
=== | === | === | === | === | === |
GND .-. GND .-. GND .-. GND .-. GND .-. GND .-.
