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 connecting the electronic components (One Photocell and one 1k Ohms resistance) to the Arduino board and the bread board as shown in the picture below. Once done, connect the Arduino board to the computer using a USB cable. Next, open the IDE, copy the code below and upload the logic to the Arduino board.o build this application, we need 3 main components: 1  A physical layer for capturing light intensities. 2  We will implement this using an Arduino micro controller and a photocell. 3  A coordination layer used for capturing the measurements from the physical layer, and sending the measurements to our application.
