Taking a look at a very inexpensive (4$ CAD) PWM module. This board has three separate channels and a very nice LCD.
PWM stands for pulse width modulation, which is basically controlling voltage going to a device by chopping up a set voltage. the higher the on-time (PWM%) the more average voltage will be sent to the device.
This module is useful for speed controlling motors, dimming LEDs and a host of other things!
Thanks for watching!

You don't need of more than 20kHz for motor PWM (just a bit higher than hearing sound). "Plate" on mosfet's gate waveform is a "Miller charge", generator has very weak output power for fast driving this mosfet (which is too powerful for this small motor). Also it's recommended to connect a diode to motor's pins for recuperate back EMF high voltage spikes.

No your videos are very good and do not need music all the good channels do not use music and you are in the with them,there is enough music on here ... keep up the good work

@felixcat4346 3 года назад

I don't think your driving the gate of the mosfet with enough current to get clean switching.

You missing the diod ( it necessary for the motor ) that why you see this signal

I could see by your plastic component container that you are Canadian. Dollarama.

1.0.1 mean 101Mhz

@stever3886

I see that some motor experiments need a “fly-back capacitor across the power-ground connections on the motor. Could this be the source of your funky waveform?

Hey finally an upload! Great job as usual, also have you considered having some soft background music? In my opinion it would work wonderfully for your video style

@SomeCatchyName

is there a place to get premade cases for these modules?

@juangizirian9810

Silly question but how am I supposed to see in realtime the duty varying on dso, I tried setting mine, but it's not showing in real time duty variation

@AnotherMaker 4 года назад

I need this. Great video!

hi,

@GeorgeJFW 4 года назад

Really cool to see how the wave behaved under high frequency low dutie cycle

@jaggi_b

Will the set frequency and duty cycle for both channels individually remain the same even after the power supply is removed? or it gets reset once the power supply is removed.

Great video. Is there a way to make this module output a negative pulse? (without reversing the leads?) I need to make a set of HI/LO (+/-) with a common ground.
