Leds however are polar. Solder one end of a copper wire to the remaining resistor lead.

The Resistor Led Pimoroni Yarr Niversity

When the solder melts remove the iron.

Where to solder resistor on led. A standard point to point connection is two leads lets say the cathode of an led and the anode of a second led twisted and soldered together. Just a small dab is all that is needed. Solder one lead of the resistor to the short lead of the red led.

How to solder a led to a resistor. Then repeat with the other wire on the other leg. Therefore polarity must be observed in the connections.

Hold the magnet wire on the led pad and heat with soldering iron. A solder pot would make it go much faster. It doesnt matter if place the resistor before or after the led because is the amount of current the resistor limits as not to burn the led.

Add a small solder bead to each pad of the leds. This is more efficient than simply just twisting leads together. Solder one end wire 2 to side b of the first resistor.

Hold the wire steady until the solder solidifies. Do this with just one of the leds. A basic instruction for electronic enthusiasts.

To choose your resistor the value in ohms voltage of your batteries or power supply as in divided by the amperage that your led needs to run. Take one of the wires red if youre color coding and do the same twist and solder procedure to the free end of the resistor. I use an rgb led and a 510 ohm resistor as i may change from 6 to 9 volts later but with my leds i could go as low as 330 ohms.

In a series circuit the current is the same for all components and because the led and the resistor are in series you can connect them as you want. Solder one end of wire 3 to side b of the second resistor. This is the most time consuming step.

Solder the free end of wire 2 to side a of the second resistor. Solder is a conductive material that melts around 400 degree fahrenheit and allows two pieces of metal to connect in a circuit. Resistors are non polar so either end will do.

The short lead of the led is the cathode negative lead. Solder the free end of wire 3 to the negative terminal of the battery to complete the series circuit.
