This slide tutorial shows students how to breadboard a circuit using two jump wires, an LED, and a coin cell battery.

Light an LED

2. About your breadboard...
Your cell battery can be attached a number of ways.
Rules for the legs/pins of the battery cell holder:
1) Both cannot be in the same connected row (there isn’t enough room anyway)
2) There must be at least 1 hole available in a row for you to plug into with your jump wire.

3. Step 1: Attach the battery holder to the
breadboard
The battery holder’s legs are positioned in row 1.
Leave a hole open on either side for a jump wire.
Be sure to press the battery holder
down into the breadboard.

4. Step 2: Add your jump wires
The red wire is shown
connected to the
positive side.
The black wire is shown
connected to the
negative side.

5. Step 3: Add the LED
Insert the positive
leg of the LED (the
longest leg) into a
hole on the left as
shown. It will be on
the same side of
the breadboard as
your red wire.
Insert the negative
leg of the LED (the
shortest leg) into a
hole on the right as
shown. It will be on
the same side of
the breadboard as
your black wire.

Note: You can gently fold
the LED downward to see
the rows better.

6. Step 4: Connect both wires as shown
Connect your positive wire to the
positive leg of the LED. Your wire must
be in the same row.
Connect your negative wire to the
negative leg of the LED. Your wire
must be in the same row.
Tah Dah! Your LED will light. You have
closed your circuit.

7. If you understand this lesson...
...you should be
able to close your
circuit in multiple
ways.
