Building the Circuit

Well, we've gone through the basics and now we're ready to complete our actual circuit.

Have a look at the breadboard diagram and connect a 330Ω resistor between the LED and the (-) of the battery. Does the LED shine bright?

Remember, you can insert the resistor on the breadboard in any way you want - it is a non-polarised component. But make sure it stands between the LED and the (-) side of the circuit (black wire).
