The longer lead always an anode terminal and shorter one is a cathode.While using an actual LED, we can find cathode and anode terminal in two ways. Similarly, we connect the negative terminal with the cathode. An anode is a positive terminal and we connect positive terminal of power supply to this terminal.
As you can depict from the diagram that it consists of two-terminal such as anode and cathode. This picture shows an electronic symbol and a physical diagram of light-emitting diodes. Traffic lights and Many others LED Terminals.For example, it is used to indicate either power is applied to the circuit or not. We usually use it as an indication signal in embedded systems projects. As its name suggests, it is a light source that emits light when we apply a voltage across its terminal. It consists of two terminals namely anode (+) and a cathode (-). How much does it require to turn it on? What is the forward voltage rating of an LED? LED Interfacing with PIC Microcontrollerīefore we see how to interface an LED with pic microcontroller, we need to understand some basics of a light-emitting diode such as its current and voltage requirements. Similarly, when we want to sense an external signal such as push-button, switch, digital signals with pic microcontroller, the GPIO pins will be used as a digital output pin. For example when we use keypad interfacing with a microcontroller or we use a switch with a microcontroller we use pins as input. Applications PIC Microcontroller LED vs Push-button useįor example, when we want to drive an external device such as an LED with Pic microcontroller, the GPIO will be used as a digital output pin.LED Sequencer Circuit using Pic Microcontroller.LED Connection with PIC Microcontroller.
