DANCING LED USING 555 & 4017 IC
COMPONENTS REQUIRED:
1)555 IC
2)4107 IC
3)CAPACITORS,RESISTORS
4)LED'S
5)CONNECTING WIRES
CIRCUIT DIAGRAM:
PROCEDURE:
Connect the 555 ic on the breadboard and at first connect the 4th and 8th pin with wire.And next connect the 6th and 2nd pin with wire,At next connect the 10k resistor to pin6 and pin 7.Next connect the 10k resistor to the pin 7 and pin8(Depending upon this resistance the blinking speed of the led can be controlled).And next connect 10uf capacitor to pin 2 and pin 1,atlast connect pin 1 to Gnd and pin 8 to positive.
Connect the 4017 IC to Breadboard and connect 8 and 13 pin to Gnd and next connect 16 pin to positive.Connect 555 output(pin 3) to 4017 14 pin.And next connect the 1uf capacitor to pin 5 and positive.Thus output comes in pin 1,2,3,4,5,6,7,9,11,12 connecting Led to that pin the Dancing Led works(The output of the pin shifts depending upon the wave generated by 555 IC and the output shift from one pin to another pin)
