today you will learn how to make a motor speed regulator (12v)
we will need
-bread board
1k ohm resistor
10k ohm resistor
transistor kt815 and a radiator to it




Assembly
here is a diagram

1 step
connect the plus and minus to the extreme legs of the variable resistor
2 step
solder a 1kΩ resistor to the middle leg
3 step
to the minus of the motor we connect the minus from the extreme leg of the variable resistor
4 step
solder a 1kΩ resistor to the base of the transistor
5 step
connect to the collector plus from the extreme leg of the variable resistor
6 step
we connect plus to the emitter from the motor

P.S controller can be connected to a circuit from this homemadebut you need to remove the gear

What does this have to do with it? You three Errors in installing the transistor!

In the text KT815, on the diagram - KT803, in the photo - KT805. )))
But this is not important in this case. It is much worse that, as an example to follow, the photo shows a triple incorrectly installed transistor.
