Light Emitting Diode (LED) adalah sebuah dioda yang dapat mengeluarkan sinar atau cahay apabila diberi sebuah tegangan. Light Emitting Diode (LED) biasanya berfungsi sebagai lampu indikator atau lampu isyarat, Light Emitting Diode (LED) juga biasanya di gunakan untuk lampu-lampu hias. Led memiliki berbagai macam warna diantaranya warna : warna rnerah, hijau, kuning, dan putih. Dalam iImu Elektronika Light Emitting Diode (LED) sering di gunakan sebagai indikator, baik indikator tegangan, input, output ataupun yang lainya.





Berikut adalah gambar Light Emitting Diode (LED) beserta simbolnya :

Pada gambar di samping dapat kita lihat sebuah contoh Light Emitting Diode (LED) beserta dengan simbolnya. Pada sebuah Light Emitting Diode (LED) memiliki dua buah kaki polaritas yaitu polaritas positive dan polaritas negative. Pada Light Emitting Diode (LED) yang bisa berganti warna biasanya memiliki 3 kaki polaritas yaitu polaritas postive 1, polaritas postive 2 dan polaritas negative. Terjadinya perbedaan warna pada sebuah Light Emitting Diode (LED) di karenakan memiliki nilai hambatan atau resistansi yang berbeda. Hal ini yang kemudian mengakibatkan terjadinya perubahan voltage pada sebuah Light Emitting Diode (LED).

LM386 AUDIO AMPLIFIER CIRCUIT

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts. LM386 audio amplifier circuit diagram The external parts shown on diagram 3.1 can be selected to get the desired gain. Circuit A will give a voltage amplification of 200. Circuit B will give a gain around 50. The circuit C is not for voltage amplification but will raise the bass level by about 5 dB. Take note that the circuit C is to be connected between pins 1 and 5 of the IC. The power output is around 550 mW at 16 ohm speaker impedance. This audio frequency amplifier is ideal for small battery powered devices. If you use the external circuit A, replace the Rx with a jumper wire in the PCB. If you use the external circuit C, solder the additio...
