Project Input for remote trigger

[ibucky]

I'm looking for some project input.

I'm want to make a remote lamp control for a room. Need someway to trigger the light on the other side of a room when you walk in. Than need to trigger it on/off from another side of the room. It's for a kids room so I'm ruling out IR remotes - they'll just loss the remote. Didn't want to tear up the floor, so wasn't thinking of a wire across the room for light beam trigger at the door. Really was thinking if I can create a fun human trigger like some taps on the floor.

The lamp is going to be plugged into a Powerswitch tail 2 connected to a Trinket and something for triggering.

It's the trigger that I'm looking for input. Any ideas out there how to trigger. Currently I'm thinking of a Motion sensor on the floor that looks for say a step pattern (three taps). I'm not sure the motion sensor would pickup the taps. I've had someone suggest a speaker upside down to capture the taps. The room does have a wood floor.

Any other ideas or thoughts? The more fun the trigger the more successful the project would be. Thank you

Have a look at this project: It might take a bit of calibration to adjust the sensitivity for the floor instead of the box, but same sensor and knock-pattern detection should be applicable.

I've made that project before, but didn't think the piezo would pickup the floor board. Guess I'll have to test. Thanks

If the piezo won't pick it up, you could try one of the microphone/amp breakout boards.

"microphone/amp breakout boards" now that sounds real promising. Wonder if this project one would be able to create 'voice commands' not real voice recognition, but a series of single syllable words or sounds could create a peak sound patterns like a knocking creates a peak sound that Steve's project could record and trigger from. If I'm off base let me know.

Have you considered PIR? It seems you just want presence detection.

The Arduino doesn't have the horsepower for extensive signal processing, but it is capable of basic frequency analysis. Search the tutorials for "FFT".

Zener - Thank you for the suggestion. I am looking for a command trigger, but a presence trigger might work as a backup.

Not sure if you could use this:
