@antonmeph A microcontroller can almost do whatever you want. For example, a NE555 timer can switch something on and off periodically. Your phone processor is a VERY big microcontroller.
@@antonmeph You can google what a mcu is. You would use it instead of a switch in this case for turning the light bulb on/off automatically (using a timer for example), or remotely if your micro controller supports it.
Not a stupid question, indeed very good. The transistor works best when the light bulb in question has to be turned on/off 10000 times in a second. Obviously a mechanical switch isn't suitable for this task. Other than that, the transistor is able to switch on/off gradually, instead of the mechanical switches which are literally binary.
Not the "simplest" explanation and the example is kinda unintuitive as it is pretty useless: you can achieve the same result by connecting the switch in series to the bulb and ditch the transistor.

Thanks for explaining this and other components. To me it very useful in understanding the pedal build videos of Josh Scott.

These videos are really amazing
Really great
Maybe a stupid question, but why we simply can't use a button, a lamp and a power source?
Good question, but what if you want to controll the lamp with a microcontroller that works at 1.5V?
@@ferdifefe3160 cool, what a microcontroller is and why would you use it to turn light on instead of a switch?

Can't you just connect base to ground to activate transistor?
The transistor in the video is an NPN transistor, which needs a positive voltage at the base to activate.

Connect the switch in parallel to the bulb? You'll short your power supply then. ;) What do you mean?

Granted, some assumptions are made of the viewer.
But then again, the creator of the vid has 60 seconds or so to put up a simple circuit.
No. It is a 1.5 VOLT battery. Not a 1.5 VOLTS battery.
Thanks for this correction.
It's another language inconsistency. 1.5 is more than one, therefore it is plural.
