I love the way he built the circuits with the wire for simplicity and also the yellow/green double arrow LED indicator. Genius!

Excellent video!!! I like the way you solder all the components to resemble the schematic. And using the LEDs to illustrate which transistor is switched on is brilliant. I really learned a lot from this video. Thanks for taking the time and effort to share this, it is really appreciated.

Thank you for taking the time to not only lay this info out, but also for the schematics on your site. Great info. Well explained.

Thank you very much for making this video. This is by far the most detail video on H bridge that I've even seen.

Great video and cool accent! Don't change a thing! :)

Im trying to make a mini RC car using an Attiny85, im going to be using an hbridge for the motor control. The problem that i have is that i only have 3 available pins to use for the motor control since 2 of the available 5 pins are being used by a bluetooth module. My question is if there is anyway to control an hbridge to go backward, forward, left and right, but do using only three input pins. Thank you in advance.

How would the dynamic braking change if u we're running a three phase motor? Would all low side or high side mosfets turn on at once, or is there a pattern that happens?

Would the H-Bridge with 4 N-Channel MOSFETs work if I only used 12V or do I need 12V and 5V?

Great video, very detailed. In the Title did you mean "Principle" you are missing the "n".

[jamespeggio]

Great tutorial, didn't understand the "pulz wife zignal" though.

At what age did you start electronics ? Just curious

[ryannicholl]

@1:30 that's not an H bridge, you have two bypass transistor circuits in parallel.

Very good video but the accent is killing me
