Step 3Add the resistors and LEDs
Add the LEDs and resistors. You will note 2 pen marks on the board. This is where the 4.5 battery pack will be connected to.
Each LED has 2 leads, with one lead shorter than the other. The LEDs are connected directly to the positive and ground power rails with the short lead going into the ground rail.
On this particular board the positive rail has a solid white shading, whilst the ground rail has just the outline.

You will have better results distributing the resistance to each LED. IE put a 16ish ohm resistor on each LED.
