Make a Night-Light

This video tutorial guides viewers on building an LED night light. It covers the necessary components, including a photoresistor, LED, transistor, resistor, potentiometer, and power supply options. The tutorial explains the circuit schematic, focusing on the voltage divider and MOSFET, and demonstrates how the circuit functions. It provides detailed instructions on wiring and assembling the circuit on a breadboard or protoboard. Finally, it shows how to adjust the circuit for optimal performance and suggests ways to make the project more permanent or creative.
