MakeCode makes it easy for anyone to make awesome electronics projects. In this one video I’ll show you how all the main blocks work as I create 15 projects. One project is a Collision Detecting Robot!

I also provide basically a complete tutorial on the Adafruit Playground Express. It is like an Arduino with a TON of sensors built in. I also show you how the Adafruit Crickit board makes it easy to drive motors, how to use Ultrasonic Sensors and so much more. Continue reading Learn MakeCode in One Video →

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 project along with me please tell me. The code follows below. Continue reading Arduino 11 Finish Pong →

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 preparation so that you can see my thinking process. All of the heavily commented code follows below.

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 processing user input along with much more. All of the code and a transcript are found below. Continue reading Arduino 9 Arduino Pong →

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 more. I hope these functions will be useful in numerous personal projects you may have.

All of the code and a transcript follows the video below. Continue reading Arduino 8 Conway’s Game of Life →

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. I’m using a 4 Bit Binary Adder 74LS283 IC to create that circuit. The circuit diagrams can be found below. Continue reading Arduino 7 Binary Calculator Circuit →

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 the basic component from which a computer is made.

I have a drawing of the circuit below to help you. I hope you enjoy this video. Continue reading Arduino 6 : Read Schematic Diagrams →

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 designs can be found below along with the code I used in this video. Continue reading Arduino Tutorial 5 →

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 we’ll learn about photoresistors, importing libraries, voltage dividers, map and much more.

All of the code follows the video below. Continue reading Arduino Tutorial 4 →

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 is below. Continue reading Arduino Tutorial 3 →

In this part of my Arduino tutorial I’ll cover how to measure current, resistance and voltage with a multimeter. I’ll also show how to measure voltage with an Arduino with a demonstration using a potentiometer and LED. To finish off I’ll show the difference between resistors in series versus parallel and a whole lot more.

All of the code used follows the video below. Continue reading Arduino Tutorial 2 →

Here I begin a massive tutorial on Arduino and Electronics! In this first video I cover Arduino Basics, Electricity, Ground, Voltage, Current, Resistance, Power, Protecting Components, LEDs, Breadboards, Arduino Coding, Ohm’s Law, Generating Different Voltages with Arduino, 2 Circuits and much more.

Like always the code I use follows the video below. The kit I’m using for the tutorial is here. Continue reading Arduino Tutorial →

In this tutorial I’ll cover the core C language used to program Arduinos. We’ll look at ports, the serial monitor, looping, data types, conditionals, setup, loop, static, functions, arrays, strings, numerous math functions, bit manipulation, random, structs, styling text, pointers and much more.

I make multiple little projects here, but the projects will get more advanced as I make more videos. All of the heavily commented code follows below. Continue reading Arduino Programming →

In this part of my electronics tutorial we’ll cover Voltage Drop, Capacitors, Variable Resistors, Potentiometers, Rheostats, Diodes, Schematic Diagrams, Electronic Circuit Diagraming Software and much more.

If you missed part 1 or part 2 definitely watch those first or you may be confused. All of the circuit diagrams can be found below the video along with a transcript of the video. Continue reading Electronics Tutorial 3 →
