- Let's use the ESP32 microcontroller and the Tip120 Darlington transistor to control high-voltage devices. The video covers the basic principles of using a transistor as a switch and the specific details of the Tip120 transistor.
Finally, we create a based password door lock system!

I always get informations about Arduino from you, thank you.
Really appreciate it
very important the part for the spike, i need a controller for a solenoid and this part is crucial for me, thank bro ❤
Glad I could help
Great work thanks!
Glad you liked it!
Cool, thanks

You talked about the spike at 2:35, I’m couldn’t see anything, what should I have been paying attention to?
Great video thanks for uploading!
Just make sure that all connections are right
I need to provide 12v switching in an arduino project. Can I do it with Tip120 transistor?
base = arduino digitalpin
collector= 12v input
emitter = 12v output
So I will use it like a relay
I don't use a relay because I need to make a compact circuit.
Is it necessary to use aluminum heatsink?
Yes, you can
ok, and what about induced overvoltage that you can have from magnets sticking to the solenoids? how do you protect the circuit from that? magic?
Diode
@@EnjoyMechatronics with overvoltage? the diode do not protect from that. maybe protect to inverted polarity
Ootoacoplador
12v high voltage?
Up to 60v
Can I replace TIP120 by TIP122?
Yeah
How amper limit?
5
this mofset have max 5amp, but you can use another mofset, there is mofset whit max amp 20amp or more, if you need hight voltage / amp maybe is better to use a relays
@@fedeyoutub IGBT (insulated gate bipolar transistor) is the ticket for high voltage/high amp loads.
Ive spent all day testing ESP32bluetooth to ESP32Bluetooth to control some 12V Leds
The circuit worked fine using the TIP120 at 12V led,
But my testing was 12v, and 24v in reality, I tested it at 24v (two LEDs in series) and it didnt work, I scratched my head for hours only to have your video show me ground commoning was needed.
As to why this worked with 12v and not 24v without joining the GND between ESP and 24v source I dont know
