Am I the only one who came to see the timing? Its 13:37...

Apart from the Mistake at 4:28 its is great stuff! Keep on posting!

4:28 "This confirms my long held view, that Networking is unnatural for a computer" -LOL, so how does plugging in a USB device and finding out that it doesn't have a driver or a correct driver lead you to such a view? How do you confuse the two?

Awesome video Peter.  I loved the mini fox hunt!

Anyhow yes micro-controller circuits are quite interesting and leave everything virtually your imagination. Keep up the good work.

seems like a lot of work for very basic automation, good vid and good luck with it :)

@flexairz computing networking's great when it succeeds and indispensible to modern life but it's still less robust and less reliable than a road or bridge which just sits there and does its job.

Experts may disagree, but to many networking remains a black art in which so many things must be right for it to work.

C'mon Peter. Networking unnatural for a computer? Really? I've been working in and around computers for more than 25 years and connecting them through all kinds of networking types and protocols.

Editing someone else's code is probably how pretty much everyone starts out, so you're well on your way to learning. I started out as a programmer long before I got into digital electronics, but I found that the underlying concepts are very similar, which helped me. Like with anything else, though, your abilities will begin to snowball over time, where learning one thing here and one thing there helps you to understand various other things, which then helps you understand more, etc.

Hi Peter, take a look at raspberry pi. It will give you a credit Card type computer with gpio on board for £15 due in next couple of weeks. Dave M0IDD

Thanks MadManMark - knew there was a better way of doing it. And I also prefer the term 'program'. I won't take you up on your kind offer - I'll teach myself one of these days. In the meantime I've found some ideas on 'brainwagon's' website that features a similar app.

I know you're just starting out in Arduino, but what you should have done is store the codes for each character in an array. That way, you can have your message stored as text, in a string. Your program (nobody really calls it a "sketch") should run through the string from start to finish, looking up the code for each character and playing it back before moving on to the next character.

If you want, I can write a program to do this for you. Send me a message if you're interested.
