Arduino Basics 1: Breadboard Circuitry

The Idea behind this series is to show you how to make electronic projects using arduinos with little to no math, or expert knowledge. In this first video, we will go over the basics of using a solderless breadboard to design, test, and build circuits for your arduino projects. I will be using a solderless breadboard (obviously), an arduino uno (for power), some LEDs, a potentiometer, 220 ohm resistors, jumper cables, a button, and a switch. #arduinobasics #arduino #basics #DIY #project #howto #tutorial #breadboard #breadboardcircuitry #circuitry #wiring #STEM #technology #guide #engineering This video, like many others of mine was filmed with the help of my wonderful girlfriend Lisa   / lisa_makesthings   0:00 Intro 0:29 What is a solderless breadboard 1:11 What you'll need 1:37 Hooking up an LED 3:27 How it works 3:56 Adding a button 4:21 Something more complicated 5:55 Conclusion 6:14 Outtro Transcript (for some reason): hi i'm noah and today we're going to be doing something a little bit different arduino basics and today we're starting with breadboards now you might ask why a series called arduino basics is starting with something that well isn't an arduino but this is what i decided to do and really you need to know breadwood circuitry in order to use an arduino or do anything interesting so feel free to complain if this offends you these are solderless breadboards they allow one to design test and build circuitry quickly and with zero cost outlay they function using rows of metal conductors which allow components to be plugged in and connected in very specific ways these connectors run perpendicular to the spine of the breadboard with the exception of the power buses on either side which one parallel they come in all shapes and sizes for example this mini breadboard has no power bus but incredibly useful for small projects the basic concept is just plug stuff into the breadboard in such a way that it connects where you need to connect and it doesn't connect when you don't want it to connect radical concept i know so let's make some circuits for this we're going to need some leds resistors jumper wires and buttons and maybe a potentiometer i've chosen 220 ohm resistors although the resistor you use is sort of flexible i wouldn't go much smaller than 220 as the leds might risk burning out but i also wouldn't go over a thousand as it would decrease brightness so i have an arduino here for power don't get too excited we're just going to use as a 5v power supply for now not doing anything fancy my first step is to connect the arduino power pins to the breadboard power bus these are the five volt pins for five volt power and the gnd pin for ground or negative connection i'm going to be using ground negative and cathode interchangeably as well as five volt and positive so if that offends you please feel free to not let me know about it thanks i've hooked my arduino up to the breadboard and now that we have power i'm going to be doing all my wiring while the arduino is still plugged in as i like the thrill of it almost like a zips in the extreme sport seriously though it's such a small amount of voltage and current we're dealing with here it can't hurt me so we're going to start by wiring up a simple led i have some 220 ohm resistors here they come in both blue and brown although they are identical in function if you don't know what size yours are just reference a resistor color chart like this one here's my led you will notice that it is red and the legs are different lengths the longer leg is the anode or positive terminal and the shorter leg hasn't quite grown in yet just kidding it's the negative terminal or cathode i had you there for a minute there didn't i so i'm going to plug my led into the breadboard making sure that the legs are in two different rows then i connect the negative terminal to the negative power bus using a resistor this is done because the led cannot handle the 5 volts directly from the arduino and will burn out if there's no resistor there to drain some of the power the resistor can be attached to either the negative or positive terminal it doesn't really matter now all that's left is to connect the positive terminal to the positive power bus using a jumper wire and it turns on you'll notice that if i flip the led around reversing the anode and cathode that it does indeed not work this is because leds are directional in fact their name stands for light emitting diode and a diode of course is just like a one-way valve for electricity...
