I am now preparing to wire up a 3point LED Cap.
I have soldered red and black wires to each LED - red to positive (pin furthest away from the flat on the LED) black to the other. I have consulted Tristan 68`s LED Assembly Wizard and it reccomends a parallel system using 15 Ohm resistors
I now wish to solder the resistors in place and take it that these should be inserted in the red wire. After that - for a parallel system - I take it that I solder the three red wires from the LED`s together and solder the three black wires together. Thereafter the red wires go to the positive side of the 4.5 volt power supply and the black wires to the negative supply side.
I have sorted the webcam out so I am nearly there.
You will deduce that my electrical knowledge is zero and you would be correct !!! so any assistance would be gratefully received.
