I have always understood H-bridges a little bit, but never thoroughly. So often with electronics, people trying to teach, talk as if they're explaining what they know to another person who already understands it. In which case, it's a great explanation. But very few people ever explain things to me in a way that I can understand it *before* I can understand it, which is, of course, the whole point. Few people even understand the difference. You do. Thank you for taking the time.

You literally teach EE concepts better than any of my college professors. Keep making videos!

[AKA]

Afrotechmods, You have no clue how valuable your videos have been to all of us. We're so glad you're back and just let us know if there's anything we can do to help keep you hear teaching us more about electronics.

From an old school audio tech I'd like to say, you did an outstanding job here! I know this does not apply directly to your video but rings true to the H-bridge. Back when I was learning analog electronics, in the day, I would have never imagined a motor controller delivering audio to a speaker but here we are. I enjoyed watching.

He's  AFROTECHMODS is back and we like very much.

Welcome back! Missed your excellent tutorials.Thank you!

[spiros]

you are great! nice to have you back in action!

[MrRoyzalis]

He's back.  Unlike most people who don't bother to take the time to make their YouTube videos succinct, you are on the opposite end of the spectrum and it is appreciated.  Your videos = greatest info per minute of video and wasted time < 1%.  I'm in on your Amazon thing.

I’m so upset I didn’t come across this channel 5-6 years ago when I did my BSEE. This guy teaches these lab topics so well!

[ataraxic]

OMG IM SO HAPPY!!! Its been two years! Since I first found this channel I have become a sophomore studying computer engineering! Your videos have really given me a head start on understanding electronics and all that good stuff.

I am from non English speaking country. Your English is not only very clear, it is sweet. Explanation was fantastic. All doubts about the H Bridge are cleared. I am in love with the channel. Thanks

[nibrobb]

After two years. It's good to have you back!

[waew]

Nice to see you back! Very nice tutorial on the basics of an H-Bridge circuit.  I'm still running about 8-9dB lower in subscribers than you - I've got a ways to go!

[bkupiec]

Glad that you came back.  Please don't make us wait two years until the next video!

The best thing about your tutorials is something always goes bang.

[YashKudale]

I am really happy to see you back in action. 

[NPJA]

Holy freaking cow. Thank god for these vids coming back.

[SirArghPirate]

Glad to see you're back. I've learned a lot from your earlier videos.

You are no longer allowed to take a break, ever! thanks for the vids
