Strobe Light circuit using 555 IC

stroboscope circuit

A stroboscope is an instrument that is used to view the object which is moving rapidly with a periodic motion as if they are at rest. The strobe light flashes at a frequency that synchronizes with the resolution of a wheel or moving object which seems to be at a still position. The strobe light circuit using 555 IC utilizes a neon lamp because their light is dim to detect the fault, for good illumination a 9-inch tube light is used.
