Do I really need resistors when controlling LEDs with Arduino?

Guide for WS2812B Addressable RGB LED Strip with Arduino

Arduino misconceptions 6: a 9V battery is a good power source. Posted on March 16, when pushing either button and powering the LED indicator. The breakdown of the project is an Arduino UNO board powering an LCD screen displaying temperature and humidity data from a DHT11 (although considering replacing with a DHT22).

Powering LED strips with as little electrical fires as possible (self. arduino) submitted 8 months ago by kylandor I recently bought a 16 foot WS2812B LED strip with …

Arduino Tutorial - Lesson 3 - Breadboards and LEDs

I'd try powering the led strip for the power-supply directly, and the arduino board via a (schottky) diode. That way the led strip will have no power when only usb is plugged in. The Arduino won't mind that it receive a bit less that 5v because of the voltage drop of the diode.

Constants are predefined expressions in the Arduino language. They are used to make the programs easier to read. e. g. light an LED that is connected through a series resistor to ground. LOW. (absorb current) up to 40 mA (milliamps) of current to other devices/circuits. This makes them useful for powering LEDs because LEDs typically use

Arduino - Troubleshooting

I want my Arduino to drive a LED strip. The LED strip in particular is the 3528 non-waterproof type. To power this up, I need a 12V power supply. My LED strip is going to be 5 meters. Now my questions are: Is it important on how many amps, my powers supply will feed? One guy did it with 12V, 5A power supply.
