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.
To measure the current in the LED circuit, follow these steps: 1  Set your multimeterâs range selector to a DC milliamp range of at least 20 mA. This circuit uses direct current (DC), so you need to make sure the multimeter is set to a DC current range. 2  Remove the jumper wire that connects the two terminal strips.
