Picture of The Embedded Arduino (smart appliances)

From the minds at

Free Arduino Kit Contest! Comment (constructively) and we will enter you in our "Win a free DIY Arduino Kit" Contest!

One of the fun things to do with an Arduino is to make your appliances smarter. From better instrumentation, to giving the appliance the ability to make decisions based on sensor input, to centralized or remote monitoring (Smartphones, etc.) and data logging, your fridge, microwave, stove, HVAC, home alarm system, etc., is ready to be Arduino-ized.

Anyone can buy an Arduino board ($30-$60 or so) and stack shields on it, but sometimes building the Arduino and the project on a single board is preferable. We will show you how to prototype a complete project on a solderless breadboard, and then move it to a protoboard for posterity.

We will be using a 840 tie point solderless breadboard, and a matching protoboard. This way all the tie points are labeled the same, and the physical layout is the same, making the transitional painless.

Step 1: Breadboarding

Picture of Breadboarding
First we will start with the Solderless Breadboard. Common sizes are 400 points and 840 points. We will be using the 840 point board to ensure we have enough space for the Arduino, the power supply, and the project.

WOW! Amazing!

Thank you.

Very nice and easy to understand. It will be helpful to me when learning about this. (I grew up with vacuum tubes, individual transistors, and 8-bit microprocessors!)

A couple of corrections need to be made though. The most important is the timebase crystal frequency. It is shown as 16 mHz but almost certainly should be 16 MHz. In the International System of Units the difference between upper and lower case IS significant. 16 mHz (millihertz) is 0.016 Hz, an impossibly low frequency for a quartz crystal. 16 MHz (megahertz) is 16,000,000 Hz which is much more likely. Also in capacitance values the F should always be capitalized as the unit is from a proper name (Michael Faraday). A capacitance value should be shown as pF, not pf.

Thank you for the corrections.

Yes putting a $25 Arduino into a permanent project makes no sense to me. And making
one is more fun than buying a nano or whatever off of ebay. I'm waiting on my FTDI so I swapped my ATMega into my real 'duino to burn the bootloader. I LOVE it!

Awesome! Keep on making!
I have an off-grid home and want to use arduino for several projects. Your tutorials look just like what I need. I recognize the great potential but know so little about electronics and programming that I feel completely stupid watching even this "simple" information. Where can I go (online) to learn what I need to know from the ground up in order to start using arduino? Thanks a lot for posting such great-looking arduino-related tutorials!

Nice tutorial. Makes it seem a little easier to get into arduino type stuff. Some pictures showing how things are laid out on the breadboard would be useful. Can see some of it in the video, but I think being able to see it in a picture would help.

A new picture on Step 2 has been uploaded showing the components laid out on a DF Robot Proto Shield. This picture,and the one on the Intro should be sufficient.

Great Instructable that makes me feel more confident about actually moving from my development board to something more permanent. It was a bit difficult for my eyes to track lines when I'd make a note on something and look up because of the information density. An ordered(numbered)/unordered(bulleted) list of parts would have helped. The formatting on the code sections weren't easy to read either, maybe a monospace font or even a link to pastebin would have made it easier.

Thanks for putting this together.

There's a complete list of linked parts on Step 2.

Thanks. One question... what about security after you have linked everything up and can remotely access. What steps do you suggest in that area?

Web based password control is common, and secure. https encrypts the communications, preventing passwords from being sent "in the clear".

Added the 10uh, 100nf LC circuit to AVCC.
