#LED CATHODE AND ANODE HOW TO#

All the project’s source codes and circuit diagrams are free and one can use and manipulate it according to its need. Each project circuit diagram, code and detail description is given in the post.

In this tutorial i am going to explains about the little difference between them and at the bottom of the post few demo projects links are given in which seven segment displays are interfaced with different microcontrollers. Which are toggled to make a specific number. Maximally you can display a digit 9 on a single 7 segment starting from 0. Seven segment display contains 7 led’s in it. But they are in used today in many appliances.

Though there use is tremendously decreased due to the invention of lcd’s. They are used to display time in digital watches, display speed of automobile in cars, on old buffers, washing machines and electrical panels etc. Also, nearly all modern light emitting diodes have their cathode, ( ) terminal identified by either a notch or flat spot on the body or by the cathode lead being shorter than the other as the anode ( + ) lead is longer than the cathode (k). This also goes for markings on a board too. With the probes on opposite leads, the LED doesnt light up The longer lead on a LED is the anode. Generally, all LED’s are manufactured with two legs protruding from the bottom of the body. Most often if you can not see any of these markings, a small notch or dot will indicate the negative side of an led.

You can find 7 segment displays on different electronic devices which display some status in the form of numbers. Polarity Guide of 0402, 0603, 0805, 1206 and most all smd leds This guide will tell you how to tell the polarity (positive/anode and negative/cathode) of leds. 5PCS/Lot 5MM 88 Dot Matrix Led Lattice Red Display Module Digital Tube Common Cathode/Anode 6060MM. 7 segment displays are kind of led displays. 50pcs F5 5mm Fog Type Two Color Common Anode Or Cathode Led Diode Red. Seven segment displays are very commonly used today. Find common anode led at for use with many different makes.
