Through a series of laboratory procedures, we have created a LED clock which is powered by a transformer whose voltage initially is a 120V rms. The purpose of the project is to understand how to use resistors, transformers, capacitors, and transistors to bring down the alternating current voltage of 120 V rms down to a safe direct current, and use that to power an LED clock.
