The slides for the TinkerSoc Practical Electronics Workshop held on 10 Oct 2009. Comments/questions to: omer@tinkersoc.org please...

1. Electronics 101 Omer Kilic omer@tinkersoc.org http://flic.kr/p/4aERQW

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

9. Diodes http://bit.ly/3f5YQt

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

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! 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!

20. Bi-stable Multivibrat0r! 270 270 18k 18k 47u 47u

21. That’s all folks… Thanks for listening, any questions? Further questions/comments to: omer@tinkersoc.org A special thanks to all the wonderful people who licensed their photos/videos under Creative Commons licenses, without them these slides would be boring as hell ;)
