Tilt/Motion Sensor #
Tutorial: Tilt Sensor Demo
This sensor demo is a simple circuit consisting of a 3V coin-cell battery, 5 red LEDs, and a 5-way tilt-sensitive switch.
The tilt switch comprises a common GND (negative power supply from the battery), which is connected to a metal bell strung on conductive thread and 5 pieces of conductive fabric.
Each piece is connected directly to the negative lead of one of the 6 LEDs and the positive leads of the LEDs are connected with conductive thread directly to the positive side of the battery power supply. When the bell rests on one of the conductive fabric petals it closes the circuit, bridging the gap between the negative power supply and the negative lead of an LED, causing the LED to light up.
