I remember it well. I also remember thinking: «What’s next?»
When you first learn to program, you approach it iteratively. You write something in the console. Then you will learn about variables and functions. Then you’ll learn how to write more adventurous programs by incorporating the code other people have written into your projects.
But building products for physical computing is not the same, because there is no such thing as logical progress. You just have to experiment and work things out as you go. I think it helps to have something to strive for and something to strive for. These six Arduino projects fit the bill.
Arduino Powered Tea Maker
Some stereotypes about the British are not true. For the most part, their teeth are in order. They’re not all stupid, polite aristocrats, nor are they all football hooligans either. Although they love tea, this stereotype is true.
I came across this Arduino kettle on Reddit. It is essentially a movable arm, powered by some servos, and made of metal and cardboard.
You can see how it works in the video above. He plunges the sachet into a glass of boiling water until the tea has dissipated enough. Then he deftly shakes the sachet into an empty bowl to dispose of later. It’s basically a Rube Goldberg hot drink machine.
Version 2.0 automatically dropped the sugar cube into the cup.
Unfortunately there are no instructions to follow, but it doesn’t have to be too much difficult to find out.
If you’re ambitious, you can improve this design by adding some much-needed features. You can install an immersion heater to keep the water warm, a color sensor to check that your cup of tea is brewing optimally, and even some speakers to periodically scold people who pour milk last.
Phone Controlled BB8 Droid
Perhaps the most requested toy was the Sphero BB-8 toy (our review of the acclaimed toy for ), which was quickly snapped up and resold on eBay multiple times at the asking price.
If you still can’t get your hands on one, why not make your own? One guy on YouTube did just that by building his own using an Arduino and a few household items.
You can see him do it in the video above. If you want to make your own, the creator has created his own how-to guide at Instructables.com.
