My Light Diagram

Flasher bulbs use a bi-metallic strip which interrupts the series circuit when the lamp becomes hot.. This is a Best Holiday Lighting Sequencer Circuit Diagram . This is Integrated circuit Ul (a 555 oscillator/timer) is wired as a conventional pulse generator. The frequency of the pulse generator is controlled by potentiometer Rll. Resistor R2 puts a reasonable limit on the highest speed attainable. The output of the pulse generator is fed to the common clock input of U2, a 74C175 quad D-type flip-flop.   Best Holiday Lighting Sequencer Circuit Diagram   Each flip-flop is configured so that its Q output is coupled to the D input of the subsequent flip-flop. Information on the D input of each flip-flop is transferred to the Q (and Q) outputs on the leading edge of each clock pulse. Switch S2 allows you to invert the information on the D input of the first flip-flop at any time during the cycle. This allows you to create a number of different sequences, which are determined...

This is the simple 10 Channel LED Sequencer Circuit Diagram Circuit diagram

Very simple, versatile modular design No limits to the number of modules used in the ring Circuit diagram using LEDs:                             Circuit diagram using Lamps: Parts: R1 1K5 1/4W Resistor R2 680R 1/4W Resistor (Optional, see text) C1 47µF 25V Electrolytic Capacitor D1 LED any type Q1 BC337 45V 800mA NPN Transistor P1 SPST Pushbutton LP1 Filament Lamp 12 or 24V (See text) Comments: The purpose of this circuit was to create a ring in which LEDs or Lamps illuminate sequentially. Its main feature is a high versatility: you can build a loop containing any number of LEDs or Lamps, as each illuminating device has its own small circuit. The diagrams show three-stage circuits for simplicity: you can add an unlimited number of stages (shown in dashed boxes), provided the last stage output was returned to the first stage input, as shown.
