Set of 200pcs 3mm clear and matt LEDs. Colors: red, blue, green, yellow, white cold, white warm. An excellent solution for bright colorful experiments with Arduino.
Light-emitting diode (LED)- a semiconductor device with an electron-hole junction, which creates optical radiation when an electric current is passed through it in the forward direction. In other words, it is a diode that has a steep current-voltage characteristic. From which it follows that to maintain the operating modeconstant current required, not voltage, otherwise the LED will simply burn out. In this set, the maximum forward current for each LED corresponds to20mA... You can limit the current for a specific supply voltage, for example, using a resistor. Calculators for calculating and selecting the value of the resistor can be found infreely available on the Internet.
