Rangkaian of lights or fold some of the usual call to the Lamp is a flirtatious multivibrator-astabil (unstable multivibrator). Transistor in the second set of this stuff to dispatch and in turn so that the LED D1 and D2 will turn on and off alternately. Flame-speed turn off the LED is determined by the size of the capacitors C1 and C2. The greater the value of the capacitor will slowly change the frequency of the second flame-out LED lights. With the value of C1 = C2 then LED1 and LED2 akan flame-out with the same frequency.
The required voltage is 9 VDC. If using a 3 Volt power portion (2 pieces battery 1.5 Volt), R1 and R2 can be omitted and the LED cathode feet each connect directly to the collectors of transistors foot related.
Sekilas kita kembali ke hal dasar yaitu tentang Cara kerja kapasitor. Kapasitor adalah komponen elektronika yang dapat menyimpan muatan listrik. Struktur sebuah kapasitor terbuat dari 2 buah plat metal yang dipisahkan oleh suatu bahan dielektrik.
Bahan-bahan dielektrik yang umum dikenal misalnya

LED (Light Emitting diode) is used almost in most electronic devices such as television, radio cassette, musical instruments, health equipment, testing devices, automotive, and others, as an indicator or signal light.
LED has many advantages rather than the other, such as: The age of a very long life, a power which is very small (energy), the response of a very fast and good.
In 1999 Philips Lumileds Lighting Company is expected to find a LED that can replace the function of light used for illumination. LED light is out with a very bright white. LUXEON LED is called. R & D office located Lumileds in San Jose and Penang (Malaysia). LUXEON presence makes a variety of new opportunities in applications that require bright light with a compact size.
following is the circuit diagram of a low cost emergency based on white light white LED LED. The provide very bright light which turns on when the mains supply is not there. The circuit has an automatic charger which stops charging when the battery is fully charged

The IC LM 317 produces a regulated 7 V for the charging of Battery.Transistor BD 140 drives the out put.Transistor BC 548 and Zener diode controls the charging of the battery.
It is always better to connect a heat sink with BD 140.Before using the circuit out put of LM317 must be set to 7V by adjusting the potentiometer.

This series consists of 10 led a mounted sequential, Supply 9V IC1A needed to strengthen to 100 times and move the audio signal IC1B. Sensitivity level of the circuit can be adjusted by changing the value of R4. The value of C4 was changed from 220 to 470nF. Each input R9 must be linked with the IC2 output pins.

IC Decoder 4017
The 4017 is an extremely useful device for project work and is used in the Games Timer and in various DOCTRONICS construction kits including the Light Chaser and the Matrix Die. When you are familiar with the 4017, you will be able to think of lots of useful applications.
Internally, the 4017 contains five bistable subunits. These are interconnected in a pattern known as a Johnson counter. The outputs of the bistables are decoded to give the ten individvual outputs.
