Midterm Project Proposal
My proposal for the Midterm Project is to create a “regulated emergency light switch”. I will be using a photoresistor, a variable resistor (most likely the 100k), a few resistors, a light bulb or/LED, power supply, breadboard, DC battery, AC adaptor, power relay, and wires. The transistor is a semiconductor device that will act as electrically controlled switch (Pg 439). The variable resistor will allow the user to set the exact amount of light wanted for the light to turn on, which will be detected by the photoresistor. The transistor will control the switch that will allow the light to turn on using battery power. The resistors are going to be powered by the AC adapter.
