LED psychedelic light KIT

Attention, the product is a KIT and therefore you will be given the components to be soldered with an electronic soldering iron and everything you need to recreate the device as shown in the image. The KIT includes easy-to-understand illustrated instructions in Italian.

EXPERIENCE LEVEL NECESSARY medium-low

Assembly and testing by Mectronica STORE is also available by adding quantity 15 of the KIT assembly service which can be purchased separately and adding it to the cart together with the KIT to be assembled.

It makes two LEDs pulsate to the rhythm of music, sounds and noises picked up in the surrounding environment by a microphone capsule.

Psychedelic LED light with microphone input, adjustable sensitivity and possibility of driving 12Vdc power lamps, it can also be useful as an optical signal for the hearing impaired. It makes two LEDs pulsate to the rhythm of music, sounds and noises picked up in the surrounding environment by a microphone capsule. It also has a Darlington that drives a power output, thanks to which it is possible to drive an LED spotlight that absorbs no more than 2 amps; with the same output it is also possible to drive an opto-TRIAC photocoupler, perhaps with a Zero-crossing Detection circuit, with which to drive a 220 VAC incandescent light bulb, acting as a spotlight: an example of this component could be the classic MOC3040 or the NTE3097. It should also be noted that the particular activation of the circuit, via a built-in microphone, makes this gadget a useful aid for the hard of hearing, since it can be used to detect the sound of the telephone and doorbell and signal it with the flashing of one or more LED bulbs also placed in multiple rooms.

Scheme in the photo: Example to create a visual alarm for the sound of the telephone or door bell. The bulb can also be LED
