Learn Crystal in One Video

Crystal is one of the most exciting new languages to come out in some time, so I decided to teach the core language in one video. Crystal is as easy to use as Ruby, but has the speed of C. In this one video I’ll cover Data Types, Strings, Arrays, Map, Looping, Conditionals, Math, Hashes, Tuples, Procs,...

Arduino 11 Finish Pong

In this video I finish creating Pong on an LCD Panel with an Arduino. I combine the code for making the Paddles work, with the code for making the ball bounce. We mainly have to consolidate printing to the LCD panel, while making sure we don’t have any character number conflicts. If you made this...

Arduino 10 : Arduino Pong 2

As we continue making Pong with an Arduino, I now create the code to make the ball handle collision detection, movement and way much more. We are building Pong on a constrained piece of hardware using raw binary bits and clever algorithms. Like before I’ll live code everything with very little...

Arduino 9 Arduino Pong

Someone requested that I make the game Pong on a 16 x 2 LCD panel and so I start doing that in this tutorial. I’m going to live code everything with no preparation ahead of time, so that you can see how I solve this problem. I focus this time on drawing on the LCD panel, moving the paddles and...

Arduino 8 Conway’s Game of Life

I tried to cover a ton in this tutorial. I’ll show how to use LCD Panels with Arduino. I then live code Conway’s Game of Life using an Arduino and a LCD Panel. Along the way we’ll create custom characters, convert from binary to base 10, generate random arrays, copy arrays and a whole lot...

Arduino 7 Binary Calculator Circuit

This tutorial takes the next step towards understanding how a bunch of resistors and transistors turn into a real computer. Previously we created gates and now we will use them to create both a 1 Bit & a 4 Bit Binary Calculator on a breadboard. I’m using a NAND 7400 IC to create an XOR Gate....

Arduino 6 : Read Schematic Diagrams

After the last video many people asked me how to read schematic diagrams so this time I’ll walk you through the process of taking a schematic diagram to a finished circuit. This time we will be creating a NAND Gate. NAND Gates are awesome because they can be used to build all the other gates. They are...

Arduino Tutorial 5

My most active subscriber asked me to show how to make a calculator with circuits and so I begin that journey with this video. To make a calculator you need to understand Transistors as well as Transistor Gates. I make 4 circuits, one to demonstrate how transistors work as well as NOT, OR 7 AND Gates. The...

Arduino Tutorial 4

In this part of my Arduino tutorial we’ll create 2 separate projects. First we’ll learn how 7 segment displays work and then create a dice simulation rolling circuit. We’ll then learn how to create a theremin, which is a weird instrument you can play without touching it. In addition...

Arduino Tutorial 3

In the last video I asked for requests so in this video I cover those requests. I’ll make both a Proximity Sensor and a Piano using an Arduino. Here is the kit I’m using. We’ll learn about Ultrasonic Sensors, How Sound is Turned into a Current, Passive Buzzers and much more. All of the code...
