Project 13: Vibration Light
Project 14: Vibration Light that Stays On
Turn on the slide switch (S1), then tap on the vibration switch (S4) or bang
on the table to light the white LED (D6) for a few seconds.
When the vibration switch is activated it turns on the
white LED and charges the 470mF capacitor (C5). The
capacitor keeps the LED on for a few seconds after the
vibration ends. If you remove C5 then the LED will only
flicker for a moment.
Turn on the slide switch (S1), then tap on the vibration switch (S4) or bang
on the table to turn on the white LED (D6). The LED stays on until you turn
off the slide switch.
When the vibration switch is activated it turns
on the SCR (W3) and white LED. Once turned
on the SCR stays on, keeping the LED on after
the vibration ends.
