I NEED a video on PWM for use with an audio circuit. PWM is great for DC motor control (cassette tape player) but it adds noise to the audio output. You should make a video explaining why and how to fix. 😬
@@igorbrichkov3632 i have a project with a microcontroller (Daisy Seed) and DRV8871 driver board, which is H-Bridge driver board and how I found this video. …I have the DVR8871 controlling the DC motor on a cassette player. But it causes a ton of unwanted noise on the output. I’m just not understand how to solve and trying to find someone smarter than me to figure it out. Haha.

Pwm and transistors next ?
I wanna do that with a salvaged USB psu "yellow" tranformer, using mosfets, CD40106 for every mosfet.
Yes. Probably mosfets

@@SISKworks thats a tall order. Have to figure out how to make a reliable pwm signal without a microcontroller first. Will work on it.

there is a 555 circuit, that allows you to control the duty cycle, using diodes and pot.
@@AnalogDude_ yes. But you need a driver on the 555 timer output like a transistor or mosfet. Will be in Next video
