  1. ELECTROVATE Anurag Dwivedi Nikhil Gupta RudraPratapSuman

  2. An Competition Basic Circuiting What is Electrovate? Innovation Debugging

  3. Problem Statement

  4. Lets Recall last Lecture?

  5. Designing a Digital Watch

  6. Electronics • Digital • Analog

  7. Digital Electronics • Similar to switches • Consists of only two states • Low corresponds to 0V • High corresponds to 5V

  8. Binary Number System

  9. Clock Pulse • Clock has 2 components :- • Rising Edge • Falling Edge • CLK

  10. Basic Tools In Circuit

  11. How do we Count?

  12. 4029 counter 4029 CLK Binary Output

  13. How to generate Clock ?

  14. 555 : Astable Mode Generates Clock pulses continuously 555 Astable Mode Output

  15. 555 : MonostableMode Generates Clock pulse when triggered 555 Monostable Mode Trigger Output

  16. Display 7 Segment Display

  17. 4 bits 7 LEDs 4029 ??

  18. 4 bits 7 LEDs 4029 7447

  19. Final Circuit 7447 4029 555 Astable

  20. Logic Gates

  21. And Gate(4081) Truth Table(A.B)

  22. OR Gate(4071) Truth Table(A+B)

  23. NOT Gate(4069) Truth Table(A)

  24. Other gates • NAND – Not of ANAND • NOR- Not of OR

  25. Xor Gate(4070) Truth Table(A B)

  26. Multiplexer(MUX)And Demultiplexer(DeMux)

  27. Multiplexer • Multiple input, one output • A single input line is connected electrically to the output • The selection of the input line is done via separate input

  28. Multiplexer

  29. Multiplexer

  30. What do we mean by “Electrical”? • Connection is analog, not digital • Any value of voltage is copied to output, and any input current is transmitted to the output • It is as if the input and output have been shorted by a wire

  31. What do we mean by “Electrical”?

  32. Demultiplexer • Opposite of multiplexing • Multiple output, single input • Input is electrically connected to one of the output lines • Selection of output line is done via separate input

  33. Demultiplexer

  34. What’s the difference? • Since the connection is electrical, same IC can act as multiplexer as well as demultiplexer • We call this Mux-Demux • In particular, the above IC is 4052 – a 4 * 1 Mux-Demux • 4051- 8 * 1 Mux-Demux

  35. Other considerations • Electrical connection is not perfect • Unconnected pins are left floating

  36. Problem Statement(Roulette)

  37. Problem Statement(Roulette)

  38. Extra features • 2 Led at a Time

  39. Extra features • Speed using LDR

  40. What do you need to know? • All information is available at the Electrovate site: http://students.iitk.ac.in/eclub/electrovate/

  41. Some rules • Minimum 3 people per team, maximum 4 • Maximum of 2 breadboards per team

  42. COMPONENTS ISSUE: 12TH AUGUST • 8:00 PM TO 10:00 PM AT ELECTRONICS CLUB IN HALL 3

  43. Some Final Words • Keep in contact with the secretaries in your hall – details are available at club website • In case of any problem regarding your circuit, contact a secretary • If the secretary can’t help you, or any other issue, contact the coordinators
