Soldering Kit: NiteLight
Soldering Kit: NiteLight
from $10.00
Take your exploration of transistors the next step beyond the TouchPad with this board that uses a a photo-transistor coupled with an NPN transistor to create a light activated circuit.

Quantity:
The NiteLight circuit further explores how to use a transistor in a logic gate to create a circuit that turns the LED on when it gets dark. This Very Useful Circuit can be embedded into any application where you need a light sensitive circuit (wearables, night lights, jack-o-lanterns).
What's included:
What does the Nitelight circuit look like?
Soldering instructions:
Extensions:
Students can even swap out the NPN transistor with a PNP transistor (not provided) to reverse the circuit and build a circuit that turns ON when in presence of light (i.e. cabinet light or refrigerator alarm).
Nitelight is also available as a pre-soldered kit.
