Practical Electronics & Circuits 101 - Intro To Signals & Systems

The second video in my series Practical Electronics & Circuits 101. This one is an intro to signals which is a fundamental aspect of circuits. I’ll be covering resistors and capacitors in my next video and will also be showing how to properly use a multimeter. In the following one I’ll be talking about voltage regulators, transistors, and relays, and at that point we’ll be ready to apply this knowledge to actual projects where we can control lights, motors, and other components from a microcontroller or a single board computer such as the Raspberry Pi.
