Running lights effect is not a new idea for electronics  hobbyist. But this multi-pattern running light becomes unique as four patterns can be selected. In the first pattern, out of eight lights, alternate light go ‘on’ and ‘off’. In the second pattern, two adjacent lights go ‘on’ and the following two go ‘off’. This pattern is shifted from left to right. In the third pattern, four adjacent lights go ‘on’ and these are sifted to right. In the fourth pattern all the eights light go ‘on’ and ‘off’ one by…

Introduction to the Strobe Light Circuit A stroboscope is an electronic device designed to observe rapidly moving objects that exhibit periodic motion as though they are stationary. This effect is achieved by flashing a strobe light at a frequency that synchronizes with the object’s motion, such as the rotation of a wheel, making it appear as if it is not moving. The strobe light circuit using a 555 timer IC utilizes a neon lamp, but for better visibility and illumination, a 9-inch tube light is recommended. PARTS LIST OF STROBE…

Telephone ringer circuit using 555 IC is a simple circuit or device which produces an alerting sound whenever a call is placed to your telephone number. The Telephone project  posted here is the a telephone ringer which produces  pleasant  tunes when a call is placed to your number. The tunes produced by “telephone ringer” here are more melodious and  soothing compare to those of old telephone instrument and piezo buzzer in the current electronic telephone instruments.
