Terminals are individually controlled by microcontroller. InĬommon anode, all the anodes of the LEDs are connected to (+) 3V and cathode What are Common Cathode and Common Anode types?ĭisplay whose all the cathode terminals (-) are connected to ground and theĪnode terminals (+) are controlled individually by an IC or microcontroller. Multiplexing helps in reducing the power consumption ofĪny battery operated device significantly, with the power consumption of singleħ segment display we can power an array of 7 segment displays. Which employees 7 segment display are multiplexed and are either common cathode Most of them are controlled by some sort of microcontroller by understanding how it works we can implement it on our own projects in efficient way like reduced cost, power consumption and number of wires that connects to 7 segment displays. Seven segment displays come across our daily life with a finished product like: microwave oven, digital clocks, speedometers etc. We will learn how to interface one to four digit-7 segment displays with Arduino. In this tutorial we are going to learn how to interface 7 segment displays (common cathode & common anode) with Arduino by using “SevSeg” library and the concept using multiplexing.
