Default Arduino beginner

I know I'm about 5 years behind the curve here but on a whim (after a suggestion in IRC) I bought the Sparkfun Inventor's Kit as something for me and my 10yo to mess around with during the school hols. We played with it for about 3 hours today and had a lot of fun turning LEDs on and off, spinning servo arms, writing rude messages on the LCD screen etc. So we're up to speed with the concepts but there's not too many other interesting projects in the manual as they're all pretty basic stuff. But we're keen to do more with it and don't mind buying a few more bits and bobs.

So, short of simply googling for more interesting projects, what's a good step from here? Has anyone got any cool projects they've done, or seen, etc? Is there a good next-step book/website for projects once you tire of the absolute beginner stuff?

I use Arduino now and then for stuff, it's great!

IMHO solving a problem of your own (however trivial the problem is and however silly your solution is) will be more rewarding than doing cookie cutter projects as you will be more invested in them, but sometimes solutions looking for problems are fun too.

Not so sure about resources as I tend to look up stuff whenever I get stuck,
but as another arduino beginner I have found the following very useful:

1. pro minis are great if you want to make something and keep it as a thing, they are cheaper (don't have an onboard programmer) and very small.

2. get a Mega if you are running out of IO on a uno/whatever the normal sized arduino is these days, much easier than messing around with multiplexors etc and they are quite reasonably priced

3. if you want to control relays and high voltage/current loads this is how I did it with ULN2803 transistor ICs

4. buy heaps of breadboard with power/ground rails and lots of jumper wires, you can use solid core network cable but it doesn't work as well.

I might try a reverse geocache as a first proper project. Basically a box that tells you how far away you are from where it wants to be. So I guess it'll consist of a mini, a GPS shield and an LCD screen.

Are there any good vendors in oz or should I get everything from sparkfun?

I've found freetronics.com.au to be pretty good locally.

internationally ebay, aliexpress etc are hard to beat on price.

You've made a good start... I bought the stuff but have yet to find time to have a play. I'm also at beginner level....

I presume you know about the arduino forum?
http://www.arduino.org/forums

and

There are lots of projects using Arduino here:
http://www.instructables.com/


Your profile doesn't mention - where are you?

Sydneyish. Lots of interesting projects on instructables, thanks.

edit: will try freetronics.. also been recommended tronixlabs and little bird.

Got all my Arduino stuff on Aliexpress. Can't beat the pricing, and delivery wasn't too bad either.

i've only got one beef with the arduino gear, it breeds like tribbles..

i got hooked after making an EDTracker which is a fun project, been using mine with with my racing sim rig.

just finished an arduino based motorcycle throttle body synchroniser for my dad. i was scratching around for a project and he'd been having trouble with his that day, we were both disappointed to find we weren't the fist to think of it but i haven't seen another one that's a standalone unit. been meaning to write up a hey look what i made post. it works pretty well, but i'd put it together blind (i'm in nsw and he's in tas) so after a couple of days tinkering and a few lessons learned in his shed during a christmas visit i'm looking forward to getting started on V2.. its name is Vacula..

made a rough signal generator when i was working on the code for Vacula that's mostly been canabalised now, generated a very rough approximation of the readings i'd get from the vacuum sensors if i had a bike to hook them up to.. hooked up a pile of leds and it made a good demo of a 4 stroke engine, had leds for each of the cylinder cycles, valves open/closed and ignition

also have a mostly completed thing that will eventually drive an instrument cluster for my sim rig.. decided to do things the hard way and it connects via udp rather than usb/serial to get the game data. only working with asetto corsa at the moment but other games with a udp interface shouldn't be a problem. it only has an lcd display now but my ebay shopping cart currently contains servo's, 7 segment and led matrix displays and a couple of small vibration motors i'm going to strap underneath the pedals for abs and traction control feedback.. the pic is missing the rotary encoder (stolen for Vacula), the video is showing she who also games playing at the other end of the house, she's got a lead foot in a real car as well..


Click to view full size!




on my to-do list is a basic oscilloscope, plenty of kits around but a. i'll have more fun doing it from scratch b. it will take much longer (see point a.) and c. it doesn't have to actually work very well to meet my very basic needs.

i've also been looking at the TV Out libraries and wondering if there's a fun tinker in that, been thinking of something along the lines of a very old school pong box and controllers..

Due to the long shipping times, It's better to buy everything, and have a bunch of stuff left over, than to not buy enough, and be unable to finish your project for another 3 weeks, because you're waiting on a single widget for $2 from china... Otherwise, you break down, and go to Jaycar and buy it for $20.

Yes. There was quite a bit of "well, it's only $2.74 for one of those so chuck it in, in case I ever need it" going on.
