LED Lamp

This is just a real project I made for myself. A little bit overmade led lamp fed by a 9V cell with light control which consists in a 20k trimmer I had, but in reality 10k was enough, so I added a 22k resistor in parallel to reduce the resistance of the trimmer. The 47k and 2.2k resistors are there to support the control of the amount of current flowing to the base of the transistor. This kind of lamps have a very low current consumption.

In my real lamp, the leds are white, not yellow.

Nice and practical build and good for newbies or returnees like me. Thanks for sharing 👍

Thanks spark379. Yeah, it's a good practice for people who is newbie on electronics. Of course is possible to build a very simple torch with one resistor and a couple of Leds, but with this one you can introduce transistors and potentiometers just for fun and practice. :)
