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.
Start by soldering a power lead to the LED. Use the cable with the female 2.1mm power jack. 1  Check the polarity of the wires. 2  Usually, the wire with the white stripe is the positive lead which is connected to the center pin. 3  Check this with the multimeter. 4  Place the LED emitter on a non-heat conducting surface.
