Hyponyms (each of the following is a kind of pan): bain-marie (a large pan that is filled with hot water; smaller pans containing food can be set in the larger pan to keep food warm or to cook food slowly).
In this simple project Iâm going to show you how to control an RGB LED (common anode) using an Arduino Uno and few push-buttons.ccording to the type of RGB LED, the 3 LEDs can share the anode or the cathode, which is the longest pin coming out from the LEDâs head. How you may guess, the other three pins are used to control the three colours.
Set the multimeter to the diode/continuity setting. Usually,the multimeter will supply enough current into the LED which will just barely light it up. The black (common) lead on the multimeter indicates the negative (cathode) lead, and the red indicates the positive or anode side. Of course, if you can find the datasheet for your LED, the pinout, along with all the other specs will be readily available on the datasheet.
