Electronic Smoke Module

Hi guys!

 

Tonight I was browsing the internet and came across an old toy robot that I had when I was a lot younger.  I then remembered that this robot basically drove around in different directions as smoke was coming from its mouth. After a little research, I found the same toy that I once had however this got me wondering if it would be possible to do something similar on one of my own robots.

 

After a little more research, All I could find about the topic was that it had something to do with vegetable oil i beleive?

Bluetooth and Arduino

Happy Holidays LMR,

Calculon is wondering if any of you have used bluetooth with arduino successfully. And if so, what did you use?

He's aware that there's an Arduino BT board, but he's looking to use a standalone module with his Mega to talk to his android phone. Anyone have any experience with this?

Would this work for this purpose?
