In this video I'll tell you what is darlington transistors, how to use them to switch medium current loads with microcontroller and what downsides they have.
Also you'll find out about darlington arrays. Of course there would be small demonstration of controlling different loads at the end of this video.

  • @JumperOneTV Nice videos! I only have one question if I may ask... : I want to amplify a incoming pulse wave that is 0 - 5V to a pulse wave that is 12V (so high is 12V and low is 0V). I want to use (darlington) transistors. Can you help me please? Thnx

  • @persiantube1990 can I ask you why you need that? to control mosfets?

  • @JumperOneTV and one more thing, where do you buy all those stuff if I may ask? Thnx

  • @persiantube1990 in local electronics shops. mostly.

  • I did know about darlingtons, but I did not know they had a higher CE voltage drop, so I learned something today. Good work Phil!

  • @lebeyes Glad I can help!

see all

  • good stuff, jumperone! my compliments. Appreciate the work you put into it. It reminds me of a PIC controller + board I have that has been lying around for years already, never having done something useful. I should get over my dis-trust of paypal, and translate my appreciation into a real world useable show of appreciation.

  • @JumperOneTV No, I had to control a kind of engine. It was for a project, the pulse that came out of a programming software could not be directly injected in the engine. It had to be amplified. So I used a darlington transistor. At the base the signal was put and at the collector I used 12V and emitter GND. So when the incoming wave was high it was raised to 12V and else it was 0V(GND). I also used a transistor at the collector for not damaging the engine. But GREAT VIDEO! THNX!

  • yeh...!! Perfetct vid for knowledge..

    Can you help me to understanding the opAmps.. I really wants to know its basics and how its work...

  • Thank you very much for your hard work and the video - all the Best!

  • vary nice the last part made me laugh

  • Awesome vids! Need more!
