Electronics tutorials using Arduino

One of the nice things about the Arduino boards & software is they let people get started hacking electronics fast. However, I was looking for a good step-by-step tutorial that helped people with almost no experience through the first few steps of microcontroller programming and basic electronics design. At the same time, I’d been flipping through Parallax’s excellent “What is a Microcontroller” workbook and decided to start writing something similar.

So check out my Arduino Tutorial page and give me feedback! Right now I’ve got 3 lessons up, and will try to get a another 3 out in the next week and a half.

  • Lesson 0
    Pre-flight check…Is your Arduino and computer ready?
  • Lesson 1
    The “Hello World!” of electronics, a simple blinking light
  • Lesson 2
    Sketches, variables, procedures and hacking code
  • Lesson 3
    Breadboards, resistors and LEDs, schematics, and basic RGB color-mixing

At the end of lesson three, you build a mood lamp!



Arduino Awesome!

Today is a crazy day, there’s tons of new stuff the the Adafruit shop.

First off, I have more Arduino boards in stock. Hopefully they will last more than a week.

Second, the protoshield PCBs are in! Hooray! This is a really nice protoshield for NG/Diecimila Arduinos


Nice! Full kits and PCBs are available.

Third, I have an Arduino Starter Pack which is a bundle of stuff that will get you going with Arduino hacking with ease!

There’s an Arduino, USB cable, proto shield kit, tiny breadboard (goes on top of protoshield), 9V wall adapter, 9V battery holder, and a bag of parts that will get you started with my Arduino Tutorial lessons 0-6

Fourth, we have all those fun Arduino accessories in the shop: USB cables, 9V battery holders, 9V regulated wall adapters, small and tiny breadboards, as well as extra Arduino microcontrollers with my “no-wait” hack that speeds up development

Yow!

Multimeter Tutorial part 3 – Voltage!

Voltage is the name of Todd Bailey’s band. This tutorial is not about that, however. It is about how to use your multimeter!

Part 3 of this exciting series sees our protagonist in AC/DC land taking care of three common tasks:

Testing batteries!

Measuring wall supplies!

Checking out wall-sockets!

Bored? Build a simple supply

This is a classic circuit, but until now I hadn’t gotten around to building one. Its useful whenever you need a floating supply or if you need a quick way to poke a signal voltage into a circuit. (I suggest it for people building and testing x0xb0x’s)
