Customer Testimonials » My first MCU/transistor controlled circuit

Love exploring with the Nerdkit. I just fullfilled a longtime goal of designing and making my first transistor controlled circuit. Pin 28 of the MCU controls the gate of the mosfet, which turns on and off an LED. Pretty basic...but something I have wanted to do for a long time. Many thanks

Hi jstockma,

Welcome to the forums! Glad to hear you're enjoying the kit.

Did you place a resistor in series with the LED to limit the on current? Also see this discussion.

Welcome jstockma I agree it was one of my better ideas as well.
I put it off for years working with 100's of discretes and Ic's and all that wiring. Then I got to thinking one of these could replace all that garbage. LOL So I am finally learning to do things the right way. LOL
