LED 'Breadboard Helper'.
You can make an 8 LED board to speed up prototyping on your solderless breadboard.
Discussed below, is an 8 coloured LED board and a series resistor board.
Images show a 'Common Cathode' circuit, 'HIGH' on Arduino outputs will turn on these LEDs.
If single colour LEDs are used, you can rotate the LED board 180° and move the resistor common to +5V for 'Common Anode'.
50Pcs SMD To DIP PCB Pinboard 0805 0603 0402 LED SMT 20.3*10mm Board (50 for ~$4.00)
Even though these adapter boards do not say 1206, you can solder 1206 LEDs on them (magnification helps 
)
