Piano sound controlled RGB LED ambilight Arduino Mega As far as I know the system first began to be used in the image on the computer monitor Ambilight the most intense color, whatever color changes the LEDs accordingly when I find a solid that was used in the TV project after share anyway Ambilight Arduino Mega on board Sound activated color changing LEDs that the system is more vumetre in a simple environment, like a lm358 2n2222 transistor outputs Arduino Mega but it’s different and a little more by adding RGB Led Strip circuit arduino RGB LED voice in addition to being used opampli applied microphone preamp lm324’s a good example about how to control it with.

Transformerless Led Lighting Led Lamp Circuit

Transformerless circuit with 220V AC LED lamp is working . Half -polar LEDs 1 uF capacitor to run the transformer is used instead . High- voltage transformerless all LEDs are connected in series to study the drawing of printed circuit boards have prepared accordingly during installation of the LEDs + – do not confuse ends .

The amount of light lamps can be used as night work is not bad . Sink, small rooms , hallway lighting in places like enough. Use of LEDs that you have McD ( light power) not less than 2000 .. Transformerless about 55 pieces of white LEDs in LED lighting circuit is used.
