Thanks so much for the reply you guys. Just got on it and ordered all the parts I needed! Yeah I think for sure a better choice for this project is the Ultrasonic detector, love the idea of getting more frantic as people get closer. Hopefully I'll be able to build this thing first! Also, can you guys recommend a good overall KIT for a breadboard and all the small transistors and such? I already have an Arduino and I've been eyeing AdaFruit but I haven't been able to get a decent one that would be concise enough for my project. Oh and as you can probably tell I am a total newbie to this whole thing so I might not be sure exactly of what I'm talking about but does anyone have a clue as to how I can go about physically soldering or connecting all these things with the speakers and the Arduino? Are there any good diagrams out there that anyone could recommend? I think I might need a transistor?
Sincerely,
Miguel
PS: Thanks for replying so soon to this forum. I had heard good things about the Arduino community and now I know they are true. Appreciate it.
