2. ELECTROVATE Anurag Dwivedi Nikhil Gupta Rudra Pratap Suman

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

4. Problem Statement

5. Lets Recall last Lecture?

6. Designing a Digital Watch

7. Electronics Digital Analog

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

9. Binary Number System

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

11. Basic Tools In Circuit

12. How do we Count?

13. 4029 counter 4029 Binary Output CLK

14. How to generate Clock ?

15. 555 : Astable Mode 555 Astable Mode Output Generates Clock pulses continuously

16. 555 : Monostable Mode 555 Monostable Mode Output Generates Clock pulse when triggered Trigger

17. Display 7 Segment Display

18. 4029?? 4 bits7 LEDs

19. 40297447 4 bits7 LEDs

20. Final Circuit 555 Astable 4029 7447

21. Logic Gates

22. And Gate(4081) INPUTOUTPUT ABA AND B 000 010 100 111 Truth Table(A.B)

23. OR Gate(4071) INPUTOUTPUT ABA AND B 000 011 101 111 Truth Table(A+B)

24. NOT Gate(4069) Truth Table(A) INPUTOUTPUT ANOT A 01 10

25. Other gates NAND – Not of ANAND NOR- Not of OR

26. Xor Gate(4070) Truth Table(A B) INPUTOUTPUT ABA AND B 000 011 101 110

27. Multiplexer(MUX) And Demultiplexer(DeMux)

28. 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

29. Multiplexer

31. 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

32. What do we mean by Electrical?

33. 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

34. Demultiplexer

35. Whats 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

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

37. Problem Statement(Roulette)

39. Extra features 2 Led at a Time

40. Extra features Speed using LDR

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

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

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

44. 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 cant help you, or any other issue, contact the coordinators
