N-FETs are like NPN transistors – the gate pin needs to have ... but only some of them will keep up when you need to drive a few meters of an LED strip. The most important parameters are drain ...

The diagram illustrates the basic design of an NPN junction transistor ... Light Touch Construct the first circuit using a single transistor, an LED, a power source, and a resistance.

These are designed to pair with a microcontroller or some simple logic-level input, but [Alain Mauer] wanted was to bring touch control to a simple LED strip ... uses an NPN transistor capable ...
