Solder the positive side to the 5V from the 7805's "O" pin, and the negative leg to the grounding strip along one of the sides, going though a resistor. It should look like this:
The resistor can go on either side of the LED, but it has to be equal to or greater than the value found using this formula:
R=(B-F)/I
R is the minimum resistor value you need, P is your battery voltage, F is the voltage used by your LED, and I is the max current that your LED can handle.
I have to save that formula and description, because I am tired of typing it out.
Code: Select all
7805(O pin)-------LED-----RESISTOR------Grounding strip
R=(B-F)/I
R is the minimum resistor value you need, P is your battery voltage, F is the voltage used by your LED, and I is the max current that your LED can handle.

can you show me a picture of you are talking about
Re: leds
what is it you don't get? the 7805 linear voltage regulator maybe? Do you own ben's book?Joes2Silly wrote:can you show me a picture of you are talking about
