As you are already aware LED has two terminals or legs:
Cathode (Shorter leg)
Anode (Longer leg)
Let us see how we can connect LED with a battery.
So, for making this circuit we will be using a online simulation software i.e. Tinkercad. If you want to learn more about Tinkercad, then please refer our Arduino coding course.
1.Open Tinkercad using www.tinkercad.com.
2.Login with your account(refer Arduino coding course).
3.Click “Create a new circuit”.
4.Search LED in the search option as shown below:
5. Now, Drag and Drop the LED to the “Designing area”.
6. Similarly, Search for battery in the search area and then drag and drop it in the ” Designing area”.
7. Now, connect the Anode leg of LED to Positive of battery(red color) and Cathode leg of LED to Negative of battery(black color).
8. You can change the color of the wire as shown below:
9. The circuit is completed. Now, for testing your circuit click on to “Start simulation button ” on the top right side.
Note : If you want to do it practically, with Led and a battery then:
-
First check the legs , longer leg is anode and shorter leg is cathode.
-
Tilt the longer leg slightly to make a difference between anode and cathode.
-
Connect anode(Longer leg) to positive of batter and cathode(shorter leg) to negative.
