DIY not gate
February 12, 2010
i tried building a not gate (1 input only), not one i saw on the internet but i tried to make one myself. The problem is i didn't succeed. Now, i know there are loads of examples of how to make one on the net, but i opened this post because i'd like to know why mine doesn't work, so i can improve, hopefully :), my electronics skills.
Here it is:
..the LED doesn't light up. how come? Oh btw i forgot to mention that the base of the PNP is connected to an MCU, and i wanted the LED to light up when the pin goes low.
Thank you for the answers, in case i forget to thank you later :=D !
