  • 2. The plan…
    A little bit of theory
    Basic Circuit Elements
    Shopping for Bits and Bobs
    The BreadBoard!
    Practical Examples
    goToKBar(); drinkBeer();
  • 3. Resistor
    TheHydraulicAnalogy
    Capacitor
    Wire
    Diode
    Transistor

  • 4. Ohm’s Law
    V = Voltage
    I = Current
    R = Resistance
    V
    I
    R
    V = Current * Resistance
    I = Voltage / Resistance
    R = Voltage / Current

  • 10. Diodes
    MAKE Presents: The Diode - http://youtube.com/watch?v=AqzYsuTRVRc
  • 11. Light Emitting Diodes
    http://flic.kr/p/38DLnC
  • 12. LEDs
    MAKE Presents: The LED - http://youtube.com/watch?v=P3PDLsJQcGI
  • 13. LED Resistor Calculation
    Let’s assume we have a 9V source…
    R = V / I
    R = (9-3.4) / (20*10-3)
    R = 280 Ω
    Nearest standard value is 330 Ω
    List of standard resistor values: http://www.logwell.com/tech/components/resistor_values.html

    Sparkfun, Oomlout, Adafruit, SKPang, Cool Components…
    eBay
    Be careful!
    Shameless Plug: http://tinkersoc.org/resources/
    (we do organise group buys and have a junk trading wiki page)
  • 19. The BreadBoard!
    * Drawn using the new Fritzing, which totally rocks!
