Multimeter

Multimeter displaying output DC voltage of 12.56 volts

Overview Power supply is a reference to the source of electrical power. Most electronic circuits require a DC power supply. The most common operating voltages for microcontrollers and digital processors are 5V and 3.3V. There are many different kinds of DC power supplies but this one is most commonly used here at ITP: – Click…

Introduction This lab will introduce you to a few basic electronic principles by trying them in action. You’ll learn how to measure voltage, amperage, and resistance using a multimeter. You will also learn about components in series vs. parallel and be introduced to Ohm’s Law in practice. For more information on the theory behind this…

9V battery snap. This flat component with rounded ends has two round metal mounts on one side. One is slightly bigger than the other, about half an inch (3-2cm) across. They are designed to snap onto a 9-volt battery. There is a pair of wires coming out one end that has a DC power plug attached to it. This can plug into a DC power jack.

Introduction In this lab you will find some of the components you’ll use frequently when making electronic circuits. For more on any given component, please check out its datasheet. There are no specific activities in this lab other than to examine the components and to familiarize yourself with them. Video: Schematics 5 – Review A…
