Multipattern Disco Lights
There are many circuits on Disco lights but most of them have a limitation about its blinking pattern. Here we introduce an LED circuit by which we can set a large number of LED running pattern. All the 100 LEDs are connected in matrix form.You can choose any colour of LED. The matrix LEDs are connected to a control circuit where two duplex circuit are used made with IC555 & IC4017. IC4017 is Johnson counter counts the pulses at pin no. 14 from pin no.3 of IC555. A potentiometer of 500kΩ is used on both the circuits. By adjusting these potentiometers we can select a dancing pattern.
The circuit diagram of the above disco light is shown below.
