Step 1: Gather Materials And Cut Out Your Heart (from cardboard)
What you need for this project:
~Four (4) red LEDs, any size/shape
~Four (4) small magnets
~Cardboard to cut the heart from
~A 9-volt battery & clip
~One (1) 330-ohm quarter watt, 5% tolerance resistor
~A soldering iron
Start out first by cutting out your two heart halves from the cardboard or other material you obtained. I just cut once by duct taping the two halves together and sketching a heart on one side.
