• 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
http://en.wikipedia.org/wiki/Hydraulic_analogy
• 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

• 17. Thanks: GurtacYemiscioglu
• 18. Shopping for Bits and Bobs
Components Suppliers
Farnell, Rapid, RS, Maplin, Digikey, Mouser…
Hobby/DIY Suppliers
Sparkfun, Oomlout, Adafruit, SKPang, Cool Components…
eBay
Be careful!

(we do organise group buys and have a junk trading wiki page)
• 19. The BreadBoard!
* Drawn using the new Fritzing, which totally rocks!
• 20. Bi-stable Multivibrat0r!
