The circuit is based on the IC1 that is 555, for the creation of alternate flashes from the two led D1-2, that can be also different colour. The frequency of alternation can be regulated from the trimmer R3 and from the C1, if changes his capacity. The supply can become from a battery or from one separate power supply. A use of circuit is creation '' clue '' of alarm. Exists the possibility is connected at the same time with D1-2, the optocoupler IC2-3, with that we externally drive circuits, for various uses. Part List R1-2= 1.5Kohm C2= 100nF 63V D1-2= LED 3mm R3= 250Kohm trimmer C3= 100uF 16V BATT= 9V Battery R4-5= 470 ohm IC1= 555 S1= Push Button or switch on-off C1= 10uF 16V IC2-3= 4N25 optocoupler visit page.

I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of the circuit is extraordinarily simple. The capacitor charges by the diode and the resistor. When...

LED or Lamp Flasher

* Flashing frequency can be varied by changing R1 value in the 1M - 4M7 range. * This circuit is very efficient when driving a small 3.2V incandescent lamp. In this case omit the LED and R3, connecting the bulb across Q2 Collector and positive supply, further reducing parts counting. *...

Basic Driver Circuits For Luxeon LEDs

These simple circuits are suitable for testing and experimenting with Luxeon LEDs, however to maintain maximum LED brightness and long life, we recommend that you use some form of current regulator such as the Advance Transformer`s Xitanium¾ LED driver or other type of current regulation circuit.

Led flasher

A relaxation oscillator is used to flash an LED in the base circuit. Cl is charged slowly through R1 by the power source, then discharged periodically through R3 and the LED by the UJT.
