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.
. . each color control pin will need its own current limiting resistor. So each color control pin will connect to an arduino output pin through its own current limiting resistor. Once that is hooked up, we can control what color the LED is by writing voltages from the arduino to specific legs of the RGB LED.If we write a voltage to the red pin, the LED will be red.s you can see in the schematic, all three of the LEDâs share a common ground pin. You can easily see that pin should be connected to your circuit ground. Now, think about how you would connect the control pins. To control a normal LED, you needed to connect to one arduino output pin.
