Circuits Intro

Circuits are everywhere around us, from your phone to the computer you're reading this from. They are necessary to support various hardware and software applications. If you're planning on working with circuits, you're going to want to get an understanding of the basics.

Hopefully the lab you're working in has a multimeter and a DC power supply. The power supply acts as a battery to provide a low and high voltage to your circuit. These voltages help induce an electrical current(s) to power various components of your circuit, such as LEDs. You can use the multimeter to measure this current if necessary.

Make sure that a high and a low voltage are not directly connected to each other with a wire. This will create a short, which is essentially an uncontrollably high current. A short can damage equipment, and burn circuit components. You need to make sure that resistance is put in place as needed.

If you've been able to follow through this guide without burning yourself/anything, then try taking a look at these resources to help you with your hack.
