Physical Computing - Arduino + Bluetooth + Gadget Control

I use my computer's webcam and microphone to switch a vacuum cleaner wirelessly. A Bluetooth module is connected to the micro-controller Arduino and paired to the computer. Arduino can only handle low output current and voltage below 5V, therefore, the vacuum cleaner is connected to another power source and I use a relay to do the switching between the two circuits. In Test 1, my processing program captures motions from the webcam and sends message to Arduino via Bluetooth. In Test 2, the program listens and analyzes the surrounding sound. It triggers on the vacuum cleaner when it captures high-pitches.

what bluetooth module did you use? was it the kc5100?

[miumiub]

@direktormikong BlueSMiRF Gold from sparkfun.com

so if the sound captured wasn't high-pitches, the vacuum would keep going on when it trigger any sound and never stop because the vacuum is noisy? :)

[miumiub]

@TheMasterAbdul Exactly! I remember I did some calibration to avoid the vacuum noise triggling

@miumiub thank you for the comment, but I the movement triggering for the vaccum, is it any type of movement is enough to make it move?

[miumiub]

@TheMasterAbdul basically, yes. I just calculated the total pixel difference between two frames. It triggers the system when the value of difference is greater than a given threshold.

@miumiub thanks for the reply, and the link! I really appreciate it :D

[TheMasterAbdul]

@miumiub thanks alot I thought it might be getting more complex to have a specific type of moment, altho it would be more sophisticated. I am thinking to do some complese things but not ready yet. I am doing my master after I just finished my BS degree in computer engineering

@kkpuzp2 i did motion sensing with processing video library and sound with Ess library (also for processing)

[kkpuzp2]

How did you do the motion capture and the sound recognition?
