Complete the CircuitElectrical Current – flow of electrons
Sunday July 13, 2014 Mission: JiggyBot 1
YOU CONDUCT ELECTRICITY!
The JiggyBot MissionMission: To build a JiggyBot that will win a race
JiggyBots are electrical devices that light up and vibrate.
Mission Targets:1. I can identify and describe the function of the components used to light up
and move the JiggyBot.
2. I can read and interpret an electronic circuit diagram (schematic).
3. I can describe the flow of electrical current through the JiggyBot components to explain how it works.
4. I can solder the components of the JiggyBot onto a printed circuit board (PCB) successfully to light up the light-emitting diode (LED) and vibrate.

Mission: JiggyBotJiggyBot Baggie Components Directions: Find this page in your lab manual
1. Open the JiggyBot baggie and get out the electronic components.
2. Match the components with the correct component name on the JiggyBot Component Inventory Sheet.
3. Use the internet or reference sheet to determine the function of each component in the kit and record in the space provided.

Mission: JiggyBotPrinted Circuit Board
• Mechanically supports and Electrically connects electronic components using electrically conductive tracts etched from copper sheets and laminated on a non conductive substrate.
• Note: Electrically conductive means that electricity can flow through the tracts and the into the components.

Device that converts chemical energy into electrical energy.
SwitchDevice used to open and close an
electrical circuit.
Resistor Limits (resists) the flow of
electrical current

LED
Light Emitting DiodeDiodes are
polarized devices. Electricity can only
flow in one direction through
them.

Breadboarding
Sunday July 13, 2014 Mission: JiggyBot 8
Challenge
• Use the breadboard in your JiggyBot baggie to practice creating a circuit that will light the LED.
• Draw the connections that worked on your worksheet by using the schematic symbols for the battery, LED and resistor.
• When you get it working – take a picture of it!!

Now it’s time to learn to solder!
Sunday July 13, 2014 14Mission: JiggyBot
Soldering
Establishes physical and electrical connections– Used by
• Electricians• Electronics technicians• Electrical engineers• Jewelry makers• Stained glass
manufacturers
Sunday July 13, 2014 15Mission: JiggyBot
Solder
is a fusible metal alloy used to join together metal work pieces and having a melting point below that of the work piece.
Composed primarily of Lead and Tin.(so we need to wash our hands when we’re finished)
Take a piece and bend or stretch it – it’s ductile!
Sunday July 13, 2014 16Mission: JiggyBot
Soldering 101• Soldering is dangerous if not respected.
• Be mindful of where you are and where the soldering iron is around you.
• If you get burned…LET US KNOW IMMEDIATELY!
• Stay together, don’t work ahead for now (For your safety)

Get your station Ready• Moisten your sponges with the water bottles
at your tables. (You don’t need standing water)
• Turn your soldering irons to 750° F.
Would like to have a picture of our soldering iron on 750
Sunday July 13, 2014 20Mission: JiggyBot
Preparing your Iron• Tin the tip of the soldering
iron by melting an inch or so of solder on the tip.
• The iron will now look shiny on the tip.
• Then wipe any excess solder on the golden sponge.
• Now place the iron back into the holder.
Tinning your soldering iron in this manner will aid in future
soldering. Sunday July 13, 2014 21Mission: JiggyBot

Strategy
Look for shinny fillets
Sunday July 13, 2014 28Mission: JiggyBot
Soldering Tips1. Make sure the tip is hot!
2. Clean & tin the tip regularlyKeep tip clean by using wet sponge and scour pad
3. Heat all parts until they are hot enough to melt solder
4. Hold the iron on the joint until the solder flashes around the pad
5. Do not use too much solder (Less is more here)Sunday July 13, 2014 29Mission: JiggyBot
Tips• Use caution when
clipping leads to avoid flinging metal across the room.
• All soldering must achieve a good solder filet on the pad as shown for circuit reliability.
• Bend resistors and diodes using needlenose pliers as shown.

Step 5
If your JiggyBot vibrates and the LED is on, then you have successfully built (soldered) your first electronic device!
Facebook, Tweet, Instagram, Vine, Whatever YOU do – tell the world
how awesome you are

Prepare for RaceYou may strategically solder legs (stiff wires) onto your JiggyBot.
All the JiggyBots will be placed in a Hula Hoop and turned on. The Hula Hoop will be removed and Your goal is to make it to the outer most ring (outlined in tape)first!

Pimp out your JiggyBot – make her spectacularly fabulous!
– Only one criteria:
She MUST have your picture on her.Take lots of pictures of her and post
