Led light based music circuit with LM3914

This is a simple light running circuit by music This circuit is not difficult, is MONO, with a few accessories. Can be connected to the output of a CD or cassette player Time.
Operation of the circuit. Begins to be input via VR. The VR will function fine, signal strength coming. D1 will take disconnected hemisphere plus leaving only the signal hemisphere removed to activation of Q1. Signal is extended through Q1 to pin 5 input of IC1. By C1 forward delay of the IC is not the LED (connected to the output. of IC1) off immediately. The IC IC1 is finished. The act shows the effect of the voltage at IC1 pin 5 of the display by the LED to pins 1-19 of the IC, which is within range. compared to a multiple voltage standard circuits. The circuit can operate effectively. In the R1 that it will determine the current flowing through the LED. To prevent LED damage.
Use should be connected to the input of the circuit. To the speaker terminals, change the value of R3 is 10k and IC1 can choose to display two types Bar (Bar) when the pin 9 and a power source. Dots (Dot) on 9-pin to float to drop.

Simple LED light based music using LM318

This is a simple circuit. Music can change the LED light level gamut.
Operation of this circuit is a circuit op amp IC1 / 1-IC1 / 5 compared to the characteristics of the circuit voltage.It has one pin acts as a voltage reference pin.That the pressure from the supply voltage and divide between R1 and R7 pressure used in this circuit will be compared with the pressure drop across R7.
As the 2V input side, it will be R2, R3, R4, R5, R6 series, keeping the pressure drop across.Each R as well.
If there is pressure to 5Vp-p is the voltage across R2 = R3 = R4 = R5 = R6 = 1V.The voltage reference, we have 2V. IC4 circuit compares the measured voltage at the input pin of IC4 is 2V.Which is equal pressure on the leg or legs plus the output of IC4 will not flow to drive the LED light will be more pressure input into this.IC4 to make work. The next LED arranged in the order of the input voltage.

Sound Light 650Watt Lamp Flasher

This is Sound Light 650 watt perform change sound of side music input be Lamp Flasher follow the level sound tone. Which there is 3 the level together , be the pitch is low. The sound is middle and tall sound. By each the group applies to ac lamp at use force against 650watt not exceed electricity and LAMP that use 6.3V or friends will use 12V sizes all right. But must use power supply 12V AC with. Besides SCR that use must durable current get tall about 4A with. The detail is other , a friend can see in the circuit yes.
