ok heres my little LED tut
heres what you'll need
-soilder iron
-soilder
-flux paste (if you want it)
-red and black wire (i used 20 gau)
-resistors 100 ohm
-white LEDs
-switch
-9V
-9V connector
1st you'll need to know that LEDs has a short (-) and a long (+) leg
plus if you look closely theres a small (+) and a fat (-) wire inside the
head
ok now you'll need to set up the LEDs bend a short leg out on one LED then on the other bend the long leg..this is called series
then add flux to one of the legs
then soilded them into series like so
now soilder a resistor to the longer leg which is the +
next soilder the red wire to the resistor then the switch
then soilder the connector to the red wire
now soilder the black wire to the short leg on the other LED
now just add the 9V and thats it
then do the same to the other side and add the red wire to the wire before the 9V and add the black to the black wire, use the electric tape to the exposed wires
