NettetLED resistor. To make sure that the LED isn’t damaged by too much current, the connection between it and the voltage supply needs a resistor. The amount of resistance needed depends on how much current the LED will use to be bright enough to see but not so much that it burns itself out. This is usually about 20 milliamps for most single color ... Nettet12. mar. 2024 · LEDs are available in many colors, including red, green, yellow, amber, cyan, orange, pink, purple, and more recently white and blue.

Nettet10. aug. 2024 · So if I use 2.5V then the current would be 50mA, which is too much to be safe for a 3mm LED. Also fits with the "get quite hot" for the resistor. For long life you probably shouldn't run the LEDs over about 10-15mA. You can measure the voltage across the resistor and figure the current, closely enough.

NettetYou should use 3 different resistors, one for each color, although the blue and green have the same specs. At 150mA the forward voltage for the red is 2.2v, green is 3.5v and blue is 3.5v.
