Blue LED indicator light for machinery lights.

Mount LED Diode on a good heatsink, a metal plate, add a fan, this is necessary because you have to "remove" the heat from the surface of the board so that the LEDs last longer to place a little bit of thermal silicone in each of the diode's placement centers.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.
Important to keep in mind the diodes generate a lot of light intensity and very concentrated.
Avoid looking directly at them once they are turned on and wear protective glasses when working with them. Characteristic: - Chip 28x47mil
- Voltage: 3.1-4.1V
- Current: 700mA

2 meter LED strip easily installed for use with Sonoff controllers via WiFi and RF. Great lights to create any ambience in any room. Change their colour and rhythm from your mobile or controller. Dance to the rhythm of the lights, copy the colour from your mobile or control the lighting with your voice assistant like Alexa or Google Home. Decorate your home with an infinite number of possible scenes. (Controller and adapter not included)

WS2812B are LEDs that have built-in logic, making it possible to vary the color of each LED individually.
WS2812B includes a integrated inside each LED, which allows each pixel to be accessed individually.
For this reason, these types of LEDs are called individually indexable.
They are based on the 5050 LED.

This module adapted for the arduino includes a laser diode and a 3-pin connector for a simple and quick adaptation with the Arduino. The diode is mainly used for laser toys, all kinds of level meter, instruments, stylus pen, mini LCD projector, remote listeners laser, alarm anti-theft light remote control. Light shots and different display can make the color of the image element a little different from the real object. The measurement allowed error is +/- 1-3 cm. Characteristic: - Supply voltage: 5VDC
- Connector of 3 pins:
1- GND
2- VCC
3- Light control of the laser diode
- Point mode: point facula
- Continuous output
- Operating temperature: -36 ° C - + 65 ° C
- Laser wavelength: 650nm (red)
