How to Use Solderless Breadboards
Step 5: Connect The Batteries!
It's all come down to
this! Hook up the batteries and your LED should light up. If it
doesn't, check the polarity of the LED, the value of your resistor (too
high a value and you may not be getting enough voltage to the LED), and
also be sure you're connected to the tie point holes as in the previous pictures. A
typical LED requires around 3v to light up so if you don't have enough
voltage due to too small a power source or too high a resistor, it may
be causing you issues.
Here's a picture of mine connected:
Conclusion
This is a very basic example of why solderless breadboards are useful. They are great for prototyping and being able to move components around at will without ruining them or having to desolder. There are also many other methods of connecting your circuit without solderless breadboards (wire wrapping, perf boards, etc) that weren't discussed, but those types of things are used as you get closer to a final design. For quick prototyping, solderless breadboards are indispensable!

Java Breadboard Simulator
Don't have a breadboard of your own yet or want to experiment away from home? Check out the Java Breadboard Simulator by Nick Glass. It allows you to simulate the circuits too, so you could build the LED circuit from this tutorial on a "virtual breadboard". Pretty neat!

Hi, can anyone please explain why putting both the LED leads into holes which are electrically common would create a short circuit? I'd say there would just be no potential difference across the LED, hence it wouldn't light up. Am I wrong? |

In the diagram showing the LED connection to the battery, the resistor needs to be connected between the positive lead of the battery and the LED. The diagram is shown backwards, therefore, the voltage will be too much and probably blow the LED. |
