| Random Number Generator by IC 4017 and 4011 Posted: 15 May 2013 06:17 PM PDT This be Random Number Generator Circuit there is the character is 10 LED Flasher by use IC 4017 and IC 4011 integrated circuit. For the 4017 IC is a 16-pin CMOS decade counter. It takes clock pulses from the clock input, and makes one of the ten outputs come on in sequence each time a clock pulse arrives. Usability press S1 forLED Flasherrespectively. By pressure (Close) S1 make LED all stick dim (Dimly). When liberate (open) S1 make LED stick bright at LED any one to one’s fate. Besides value expansion C1 be 4.7uF make LED flasher slow down. The detail is other invite friends see in the circuit leisurely.  |
| LED Chaser by IC 4017 + IC 555 Posted: 15 May 2013 05:50 PM PDT I believes in that extremely amateur electronics many you, may ever build the LED flasher or light blinks or the LED Chaser prevent come to already. Today I begs for to advise the circuit LED Chaser, by have LED show 10 amounts together. blink stick bright chase go to continually. By have IC CD4017 circuits precede at drive a tube LED all. Which its work be Counter circuit good just this besides. Still have IC 555 wait for feed Clock with then can fine the speed of the winking with VR1 good easy. The detail is other see in circuit picture better. Circuit LED Chaser by IC 4017 + IC 555 4017 Led Pattern-Flasher The circuit uses a 555 timer oscillator to supply clock pulses of a variable frequency to the 4017 decade counter. The decade counter only needs to have three outputs so the fourth output goes into the [...]  |
| Posted: 15 May 2013 05:44 PM PDT This the circuit light led flashing with show of 10 LED. By use integrated number circuit CD4017 perform be Decade Counter/Divider with 10 Decoded Outputs. Which it is integrated digital circuit CMOS then use the power supply about 9VDC. For a signal input continue the circuit can produce general frequency may use IC NE555 all right.  |
