This circuit is a prototype of a simple LED chaser circuit (like the lights from night rider). When set up, this circuit will drive 6 led's in a chaser motion. This simple circuit uses only two ic's, a 555 timer and a 4017 decade counter. The circuit is split into two portions, timing and output. The timing section is powered by the 555, and sends a pulse to the clock pin of the decade counter. A variable resistor controls the flash rate. Each time the decade counter gets a pulse from the ...

This is the sound and light effects circuitry in development The top board has a 555 monostable timer, which turns on a bright red LED, a laser, and the sound effect. It also triggers a second board, which has 555 oscillator which is triggering a 4017 decade counter chip. That circuit is the blue LED chaser. I have it timed so that it goes one cycle during the time that the trigger from the first timer is high. Whew! a lot of work ... Views: 22,742 |

Low Voltage Test of my home made LED emergency/hazard lights on my car. there are some on the back, which you can see the reflection of in the windscreen. Specs: 2 banks of 8 leds on the front and 2 banks of 4 leds on the back, the lights are driven by a 555 timer and a 4017 decade counter this is running at lower voltage then it could will fix that latter.

A little circuit I made; the components used are, in clockwise order starting from the small chip: - 555 timer (to generate a clock for the other ics) - 4017 (decade counter), with actually only 8 leds; it resets on the 9th output - 4510 (BCD counter) - 4060B (binary counter), with just 4 leds; it resets on the 5th output The upper "spurious" yellow leds is used as a monitor for the clock; the on the right is pretty much pointless, as I'm not using the carry output of the 4017 for anything ...

This is a simple analog step sequencer with 10 steps. It's loosely based on the baby 10 sequencer. It generates 10 different control voltages (CV). In the background you can see the Simplesizer, a simple analog Synth which I built recently. The sequencer controls the synth via CV. Gate/Trigger is in the planning but not functional yet. The circuit of the sequencer is actually quite simple: A 555 timer IC generates a pulse signal which acts as a clock signal for the 4017 decade counter IC ... Views: 839 |

This circuit uses the 4017 decade counter and a 555 square wave generator for the clock. Common questions I've been getting about this video. Q) How did you get it to go back and forth? A) By means of the 4148 Diodes. These allow 2 outputs to be connected to one led, thus giving the back and forth movement. Q) can i haz schematic?
