This is what I have so far.
I'm familar with how to make a NOT gate with a single N-Channel Mosfet. It's pretty simple.
So when the LDR get's light, it normally has very low resistance, and allows current & voltage to pass.
So when the LDR get's NO light, the resistance is very high, and current & voltage is NOT allowed to pass.
So in my n-Channel MOSFET NOT gate type circuit, I simply have a voltage going into the gate, or not going into the gate.
The LED is ON when there is NO voltage going into the gate, and LED OFF when voltage is allowed to go into the gate. Pretty simple.
I made a video a little while back, and the circuit works.
So I basically put an LDR at the gate, and when it sees light, the LED(s) are OFF.
Because the LDR is allowing current & voltage to go into the gate.
The voltage and current takes the path of least resistance, and doesn't go threw the LED. The Drain & Source have less resistance.
Is my circuit good? I would also, when it get's dark outside, or starts to get outside, I want to go outside, and adjust it to that much light. Probably with a Potentiometer.
But I'm confused how the Potentiometer allows me to do that..
