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.
1 If you have a turntable that you want to stop at several positions, use a single microswitch and place several bumps on the edge of the turntable where each bump closes the switch as it passes by. 2  If you want to stop the motion at the beginning and end of travel, use two microswitches wired in parallel.or regular switch action, connect to the C and NO terminals. The switch will be open when not pressed and closed when pressed. Interface your microswitch to the Arduino in the usual manner as shown here.
