mrx – If you’re just turning the motor on, you don’t need the diode. However, the first time you turn it off could also be the last time because the switch is damaged. This means you might not be able to turn it on a second time. (Notice that I didn’t say anything about what’s doing the switching.)

Very nicely done videos!

@mrx: you always need a flyback diode. a motor can come to a sudden stop, or imagine what happens when it’s not moving but someone turns the rotor.

The flyback diode is really a good point.

Though, I think I don’t need it if the
micro-controller powers the motor using a smooth
transition from the off state. Am I right?

Their videos are always excellent, despite some basic topics they cover everything so clearly that it is great for explaining things.
