Complete the Circuit Electrical Current – flow of electrons YOU CONDUCT ELECTRICITY! Sunday July 13, 2014 Mission: JiggyBot 1 The JiggyBot Mission Mission: 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. Sunday July 13, 2014 Mission: JiggyBot 2 Mission: JiggyBot JiggyBot Baggie Components Sunday July 13, 2014 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: JiggyBot 3 Mission: JiggyBot Printed 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. Sunday July 13, 2014 Mission: JiggyBot 4 Mission: JiggyBot Battery Device that converts chemical energy into electrical energy. Switch Device used to open and close an electrical circuit. Resistor Limits (resists) the flow of electrical current Sunday July 13, 2014 Mission: JiggyBot 5 LED Light Emitting Diode Diodes are polarized devices. Electricity can only flow in one direction through them.

Sunday July 13, 2014 Mission: JiggyBot 9 Challenge Build a Resistor-LED circuit Schematic PREDICT: Why do you think it is necessary to use a resistor with the LED? Sunday July 13, 2014 Mission: JiggyBot 10 JiggyBot Altium Sunday July 13, 2014 Mission: JiggyBot 11 JiggyBot Schematic Sunday July 13, 2014 Mission: JiggyBot 12 Next Challenge * Breadboard your JiggyBot components* Sunday July 13, 2014 Mission: JiggyBot 13 Now it’s time to learn to solder! Sunday July 13, 2014 Mission: JiggyBot 14 Soldering Establishes physical and electrical connections – Used by • • • • • Electricians Electronics technicians Electrical engineers Jewelry makers Stained glass manufacturers Sunday July 13, 2014 Mission: JiggyBot 15 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 Mission: JiggyBot 16 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) Sunday July 13, 2014 Mission: JiggyBot 17 PCB – Printed Circuit Board Sunday July 13, 2014 Mission: JiggyBot 18 PCB – Printed Circuit Board Soldering Pads Top View Side View Circuit Board Component Sunday July 13, 2014 Mission: JiggyBot 19 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 Mission: JiggyBot 20 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.

This will drag solder up with it. Solder Sunday July 13, 2014 Mission: JiggyBot 27 Strategy Look for shinny fillets Sunday July 13, 2014 Mission: JiggyBot 28 Soldering Tips 1. Make sure the tip is hot! 2. Clean & tin the tip regularly Keep 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 Mission: JiggyBot 29 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.
