WindChimeLED
Arduino based LED reactive wind chime.
Premis
- the wind chime center weight swings and knocks the tubes
- sensors pick up knocks and trigger the led's
- led's quick on, then fade off
- led's brightness determined by knock value
Equipment
- Wind chime (6-tubes/bamboo)
- Arduino (Pro Mini)
- Accelerometer
- 6 sensors
- 6 LED's
- Copper tape
Setup
- LED's are mounted in the bottom of the tubes (i drilled a hole through from the top)
- knocks on the tubes are picked up by
- (a) piezo sensors mounted on the tubes,
- (b) tilt-switches mounted on the tubes,
- (c) corresponding copper strips on both the center weight and the tubes (connecting to make circuit),
- (d) piezo strip mounted around the center weight (triggered by collision with tubes),
- (e) accelerometer chips mounted on the tubes.
Testing
- Sensors tested
- piezo,
- tilt-switch,
- copper strips (connecting with center weight)
- Sensors NOT tested (more expensive)
- piezo strip with weight,
- accelerometer chip
