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: - 32mil Chip

Arduino has decided to further develop its catchy Nano project in the direction of more power. Nano Every is the simplest of the new series as it doesn´t include any sensors nor connectivity solution, however still significantly more powerful than standard Nano (50% more program memory and 2 times more RAM). Above characteristics make it perfect for projects of small devices with more advanced functionalities, such as audio processing or robotics.
