In this lesson we will create a night light that turns on when its dark and turns off when there is light.
Recall Lesson 4 where we used a LDR that made a light and buzzer turn on when there was light and turn off when there was no light. Now we want the opposite to happen so we can use the NOT gate from Lesson 5.
All components can fit in a single board if you only have one. Otherwise just connect the prior two lessons as shown.
Next we will see how make the OR and AND logic gates and use them in some useful circuits.
