I supposed it to be the resistor, but powering the LED directly, it was shining at full current. I started with lots of measurements and discovered that through the LEDs was flowing a current of only about 3.3mA, as You can see in that picture: saw that the LEDs where much more dimmed than when driven by the transistors. Then I turned on the circuit with great expectation and. So I bought some 2N7000 ones and replaced them on my breadboard making them correspond with the place of the BJTs, so Gate to the Base, Drain to the Collector and Source to the Emitter. I'm making a police-style led flasher for an RC car and decided to drive the LEDs using MOSFETs instead of transistors, for obvious Gate Current advantages. I want to share with all what happened to me, why I was being wrong and what I learned:
