Project 105 tilted motion detector, Project 106 tilt off – Elenco Snap Circuits Motion User Manual
Page 56
Build the circuit and turn on the slide switch (S1). One of the LEDs (D8
& D10) lights if the circuit detects motion in the room WHILE it is being
tilted at some angles. Experiment to see which tilt angles activate which
LED.
Project 105
Tilted Motion Detector
Build the circuit as shown, set the lever on the adjustable resistor (RV2)
to the right, and turn on the slide switch (S1). The red/yellow bicolor
LED (D10) is on unless the circuit is tilted or moved.
If the LED is off when the circuit is left alone on a flat surface, then tilt it
slightly so it turns on.
If desired, reverse the orientation of the red/yellow bicolor LED, or
replace it with the color LED (D8, “+” on left).
Project 106
Tilt Off
-55-
The tilt switch (S7)
contains a ball, which
activates contacts when
it rolls to either side due
to tilt or motion.
