LED Series Connection

In the following project, we are going to create a circuit where the LEDs are connected in series.

Components Required

9V Battery with Connector
3 LEDs
220Ω Resistor
Breadboard
Jumper Wires

Circuit Diagram

Step-by-Step Guide to Connect the Circuit

Step 1: Get the Power Ready

  • First, connect the red wire from the battery clip to the long red line on the breadboard. This is the positive (+) side.
  • Connect the black wire from the battery clip to the long blue or black line on the breadboard. This is the negative (-) side.

Step 2: Place the Lights

Now for the little LED lights! They have one long leg and one short leg. Make sure you place them just like in the picture.

  • Find row numbers on the side of the board.
  • Plug the first LED into rows 7 and 8.
  • Plug the second LED into rows 12 and 13.
  • Plug the third LED into rows 17 and 18.

Step 3: Add the Resistors

  • Plug the resistor in row 18 as shown in the diagram.

Step 4: Connect the Wires

  • Plug one end of the wire into the negative (-) line and the other end into row 8.
  • Plug one end of the wire into the positive (+) line and the other end into row 18.
