Similarly, one BS170 mosfet was used in my prototype to drive the 3 x White LEDs strip. This part number (and ofcourse the LED type) is not very critical. If you want to use a bi-polar transistor, don ...

A 2N2222 NPN transistor is responsible for connecting the ground rail of the LED strips mounted under each shelf. The base of that transistor is held high with a pull-up resistor.

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming. … ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

If you're looking for a way to spice up your boring staircase, DIYer Geert shows off a simple way to safely light up your stairwell with programmable, color changing LED strips mounted directly to ...
