Building a Simple Circuit
It's now time to build our first circuit.
First we are going to build a simple circuit that will make a Light Emitting Diode (LED) light up.
Remember, if we don't use a resistor in our circuit then there will be too much power for the LED and it could burn out or even POP!
Make sure that you use a resistor and that it is in the right spot.
Build the following... but remember...
- the resistor needs to be in the right spot
- the pos (+) and neg (-) of the battery have to be properly matched with the pos (+) and neg (-) of thebreadboard
- LEDs have a pos (+) and a neg (-) side, pay close attention to this. The short leg and flat edge is neg(-) while the long leg and rounded side is pos (+).
Touch the negative wire to the negative side of the battery and the positive wire to the positive side of the battery.
Your LED should light up, if it doesn't then you need to troubleshoot the circuit and figure out what's wrong.
