Guys, if you're reading this, please subscribe to my channel. This channel really got screwed over by demonetization day. I can't do it without you. Thanks.
Thank you SO much for this. I am working on a project with a startup and needed an intro to some CE type concepts.. Discovered your channel, you have a handful of super helpful videos. Hope you keep it up, subbed to see.
The word 'connector' suggests something which connects other things. It's more usual to say the transistor is a three terminal device. In discrete form the terminals may be called 'pins' or 'leads', but NOT 'connectors'.
Nice tutorial. You do a nice job of explaining each component. Very easy to follow. Would love to find some info on DS3231 RTC / Arduino coding, not just time setting, but coding it to make turn loads on. Hops to see more of your videos.
would you please do a video on encoder circuits using photodiodes and op amps!!? You have the best explanations. I the idea of amplifiers didnt make click for me until i watched this. Also if you just did an explanation of Op amps by themselves that would be awesome too. Cheers!
Depends on what the current drain rating is for. Is that the stall current (seems like it would be because it's incredibly high)? If so, the 32A is a worst-case scenario for when the motor is lifting an "infinitely" heavy load and cannot spin (heavy load = more power usage -> makes sense). That's an unlikely case for most applications. I talk more about this on my videos about H-bridges. Edit: Make sure you're using power transistors for those currents!
Thank you for writing such a detailed reply. Though I am a mechanical engineering student, I was assigned with this project which I know little of.In the tech. specs. there are three different current values Idle: 2.0A curr. drain at max efficiency: 32A blocking current drain: 150A I have to drive a propeller with this motor so I hope using a mosfet, and a couple of diodes to eliminate the inductive spiking, would solve the problem. :)

This is the best transistor tutorial I've ever seen!

Enjoy the subtitles. The automatically-generated ones kept mistaking 120 milliamps for 120 million amps - so I thought I'd update that :D.

just found a gem. Thankyou my friend

Thanks for the suggestion. I've done projects like that before. Maybe I'll do a programming tutorial at some point in the future if I have time.
thanks a lot I tried other methods but only this worked
thank you for the great tut its well informed and helped me out alot
you sir deserve a sub and a thumbs up
shouldn't the Arduino input be grounded back to the Arduino?

Great tutorial! What software are you using? I usually use LTSPICE but this seems a little more user friendly.
Yea I've never been a huge fan of spice. It's pretty powerful but I hate the UX. There are links to the simulators I'm using in the video description.
I have a question :)
my dc motor has a nominal voltage of 16V and a current drain of 32A... should I really model it as a 0.5 Ohms resistance?

thanks a lot.
Is the transistor in the final sketch a NPN? so the pins are collector, base, emitter, from left to right?
