Step 9Readying and attaching the Relay
For this step you will need your power inverter, relay, and 9V snap connector
The following link is the specific relay used in this project:

The jersey will work with practically any relay with a normally open/closed output and that can handle 9V so feel free to use whatever is accessible to you.
NOTE: For EVERY connection made in this step it will be expected that you slip heatshrink onto one of the wires prior to soldering, and then proceed to cover the connection with the heatshrink after soldering.
Solder a lead wire onto each of the pins extruding from the relay.
TIP: Take the lead that you are going to solder to a pin on the relay and wrap it tightly around the solder you are using so it makes a sort of coil. Then pull the solder out and, without undoing the coil, slip the lead onto the relay pin. Since the relay pin is fairly inflexible and is also similar in size to the solder the coil should fit snugly around the relay pin, keeping it steady for you to solder a good connection.
Solder the Positive DC Load pin of the relay to positive wire of your 9V snap connector.
Next, solder the negative DC Load pin of the relay to the positive wire from the power inverter.
Next, connect the positive DC Control pin of the relay to Pin 5 on the arduino in the same manner that all connections have been made thus far to the arduino.
Next, mark with a piece of masking tape the negative DC Control pin of the relay as "NEGATIVE" and leave aside.
Finally solder the negative lead of the 9V snap connector to the negative lead of the power inverter.
