This square wave generator uses two potentiometers which can vary the frequency and duty cycle. This can drive a stepper motor square wave signal and can be used to control motors (PWM generator), adjust brightness in bulbs and LEDs or timers. It also features an adjustable pulse control circuit.
Surprins de bun
Bun modulu doar ca pe primul lam ars ca nu este specificat cu ce trebuie sa conectezi OUT-ul, dupa ce sia dat sufletul la primul miam dat seama ca e defapt GND (negativul de la baterie/sursa), miam loat iar modulul (pe al doilea) si sunt super multumit de el si faptul ca are precizie mare la control si o frecventa frumoasa asa cum trebuie.
Recomand acest modul.
testat pe osciloscop
Potentiometrele multitura sunt precise dar invartesti la ele de faci muschi la degete. Este un modul foarte bun pt. invatat si pt. aplicatii cu semnal pwm. Se pot regla frecventele din jumperi.
