  1. EssmartHackathon Peter Burkimsher and SreechandTavva

  2. What to expect • A basic introduction to electricity • How to read a circuit diagram • Common electrical components • Series and parallel circuits • What not to do • Advice for best practice • Build your own multi-brightness LED!

  3. Electricity - 1 V+ GND

  4. Electricity - 2 V+ GND

  5. Electricity - 3 V+ GND

  6. Voltage - 1 5 V V+ GND

  7. Voltage - 2 2.5 V V+ GND

  8. Voltage - 3 0 V V+ GND

  9. Current - 1 V+ 0.001 A GND

  10. Current - 2 V+ 1 mA GND

  11. Current - 3 V+ 500 mA GND

  12. Shorting out 5 V GND 500 mA V+

  13. Circuits 5 V GND 500 mA V+

  14. Resistor 100 Ω 4.7 kΩ 5 V 20 mA GND V+

  15. Diode GND V+ 5 V GND V+

  16. Diode warning 5 V GND 500 mA V+

  17. LED GND V+ 5 V GND V+

  18. Practical 1 – Series LED

  19. Practical 2 - Switch

  20. Switches 5 V 0 mA GND V+

  21. Practical 3 – Series Resistors

  22. Practical 4 – Parallel Resistors

  23. Variable Resistor 5 V GND V+

  24. Practical 5 – Variable Resistor

  25. Practical 6 – Parallel switch

  26. Thank you for your participation!

  27. Practical 8 – Everything • Let’s use everything we learned to build a full circuit with all the features we want! • The switch activates maximum brightness • The variable resistor controls brightness

  28. Practical 5 – Voltage Divider • A voltage divider places the LED in parallel with the second resistor. • This should be half as bright as when the LED was in series with only the 100Ω resistor.

  29. Changeover Switch • Changeover switches let you choose 2 inputs. • If one pipe is empty, a changeover switch is the same as a normal on/off switch. • Our switches have 3 connectors for this. • We will leave one disconnected. • Electronic symbol: 5 V 0 mA GND V+
