I've noticed (like many of you already have) that servos don't connect too easily to breadboards(or arduinos). While you can use a male pin header to connect servos and breadboards, why not just create a Servo that can connect without any extra parts? Here's my simple solution, I'm sure its been done before, but here's my step by step guide on how to complete this simple 5 minutes project.
Step 1: Gather the Materials
For this project, you'll need a few things.
A Soldering Iron
A soldering iron can be purchased at quite a few places. For electronic work you'll want a lower wattage iron, try checking out radioshack.
Three Breadboard Wires
Breadboard wires have pins on each end, which make it very simple to plug them into breadboards and pin headers. I purchased mine from adafruit.com, it is a very reliable site, which also sells everything else needed to complete this project.
Here are the breadboard wires that i bought www.adafruit.com/index.php
This is very self explanatory. You need this for clipping and stripping the wires.
This is for joining your wires together. Check adafruit.com or radioshack.
These can be found on many hobby stores and websites. I actually purchased mine from amazoncom.
The heatshrink wrap is for insulating your bare solder joints. this can be purchased from radioshack or any other electronic parts supplier.
Step 2: Cut Your Wires.
The first step, is to cut your wires. Grab your breadboard wires and cut them in half with the wire cutters. Then take your servo wires, and cut them just before the connector. My servo didn't have a connector, because i cut it off a few months ago.
Step 3: Strip!
Now it's time to strip your wires. Grab a wire about 3 or 4 mm from the end of the wire, and then light clamp down on the insulation on the wire. Then pull the insulation off the wires. Do this to all your bare ends.
Step 4: Tin Your Wires.
Now it's time to tin your wires. This means your going to coat your bare ends in solder. Touch the wire to the tip of the soldering iron, then touch the solder to the wire. Give it a few seconds, then you'll see the solder melt to the wire. Do this to all your wires.
Step 5: Heatshrink Wrap
Cut three pieces of heatshrink about 1/2 to 3/4 of an inch long. Slide one over each wire, when we're done soldering the wires, the heatshrink will slide over the joint and cover it.
Step 6: Connect the Wires
We're almost done now! Now you need to take one wire from your servo, and one breadboard wire, and solder them together. This is almost exactly like tinning your wires except you need to take both wires and solder them together. Make sure the wires are straight when you connect them, so you can slide the heatshrink over the connection when your finished.
Step 7: Shrink the Heatshrink
Slide the heatshrink over the joint, and make sure it is centered. Now take a lighter, matches, or a hot air gun and heat the heatshrink wrap until it is tight against the wire. Don't burn the wrap though!
Step 8: Enjoy!
Your all done! Now go enjoy your new breadboard compatible servo motor!
