Course Description

This course is designed for beginner makers. I will help you get started with the basics of creating circuits with the Arduino prototyping board, and by the end of this course you will have an Internet-connected home environment monitoring gadget, build with your own hands!
The only prerequisite is a basic understanding of concepts like voltage, current and resistance, and ability to download and install software on your computer. A very basic understanding of programming is a bonus, but not absolutely necessary.
Along the way, you will learn about programming, sensors, and communications.
The course is split in three parts:
Part 1 is an introduction, which will gently help you create your first circuit and open your appetite for more.
Part 2 contains a primer on making with the Arduino, focusing on the Integrated Development Environment and the sketching language.
Part 3 is about making JING. JING (not an acronym!) is the environment monitoring system that you will put together piece by piece, and line by line.
If learning by making sounds like the way to go, then this course is for you!
Materials:
To fully take advantage of this course, you will need (all of these are easily sourced from Ebay):
1) An Arduino (I suggest a genuine Arduino Uno)
2) A photoresistor
3) A DHT22 temperature and humidity sensor
4) A BMP085 barometric sensor breakout
5) A 16x2 LCD screen based on the Hitachi HD44780 driver (or compatible, these are very common)
6) A potentiometer
7) Assorted resistors
8) A small breadboard
9) Lot's of breadboard wires. Who this course is for:
  • Makers who have an existing intermediate or better understanding of electronics
  • Beginner Arduino makers

Great little project for the Arduino UNO

By Nick Fiorentini

Awesome course with a very awesome instructor!

By V Hays

a tad slow. i like your later videos better. running it in udemy at 1.25 speed works better.

By Matt Tucker

There really is no excuse for having mistakes in a video lecture, even seemingly innocent ones that the demonstrator corrects immediately. That is what video editing is for. Cut out your mistakes.

For instance, if you highlight code from the Arduino website and say "I'm using this function format", then cut back to a shot of your IDE code, then back to the website and say "No, actually I'm using this section" and then highlight a different section. WHY? WHY? WHY? Just edit your video! Don't show incorrect information, only to follow up with something different.

In just one video there are multiple mistakes. Navigating to the wrong section of the Arduino website, then correcting it. Highlighting the wrong section of code, then correcting it. Calling something a "constructor" and then putting up a text box "Sorry, this is a function, not a constructor". Why would anyone make a video with so many mistakes? Just fix the mistakes BEFORE you post the video.

By David Batty

This is a well structured, clear, easy to follow course. If you want to learn to use an Arduino and understand some electronics for beginners then I recommend this course.

By Rene Nessler

The content is really good, thanks.

Please consider removing the music, it is not helpful.

By Torsten Philipp

Thanks a lot for this course.

Very good structure and many interesting information.

By Jesus Solano

Very very informative about the potential of Arduino

By H Fernandez

Es muy claro en sus explicaciones aunque debería de dar más ejemplos de programas para reforzar los conceptos.

By Vagelis Chantzis

The course is well explained and well organised by Dr.Peter. He makes everything clear and motivates you to make it on your own. Absolutely recommended course if you are interested in Arduino​!!

By Ellis Whitehead

The instructions are very understandable even if you are new to programming. I like the instructors presentation style and how smoothly the content progresses from one topic to the next with clear examples of how the code works.

By Karnak Roy Chowdhury

IT is an awesome experience to learn ARDUINO from basic to IOT .
