Slide 2 ELECTROVATE Anurag Dwivedi Nikhil Gupta Rudra Pratap Suman Slide 3 What is Electrovate? An Competition Innovation Basic Circuiting Debugging Slide 4 Problem Statement Slide 5 Lets Recall last Lecture? Slide 6 Designing a Digital Watch Slide 7 Electronics Digital Analog Slide 8 Digital Electronics Similar to switches Consists of only two states Low corresponds to 0V High corresponds to 5V Slide 9 Binary Number System Slide 10 Clock Pulse Clock has 2 components :- Rising Edge Falling Edge CLK Slide 11 Basic Tools In Circuit Slide 12 How do we Count? Slide 13 4029 counter 4029 Binary Output CLK Slide 14 How to generate Clock ? Slide 15 555 : Astable Mode 555 Astable Mode Output Generates Clock pulses continuously Slide 16 555 : Monostable Mode 555 Monostable Mode Output Generates Clock pulse when triggered Trigger Slide 17 Display 7 Segment Display Slide 18 4029?? 4 bits7 LEDs Slide 19 40297447 4 bits7 LEDs Slide 20 Final Circuit 555 Astable 4029 7447 Slide 21 Logic Gates Slide 22 And Gate(4081) INPUTOUTPUT ABA AND B 000 010 100 111 Truth Table(A.B) Slide 23 OR Gate(4071) INPUTOUTPUT ABA AND B 000 011 101 111 Truth Table(A+B) Slide 24 NOT Gate(4069) Truth Table(A) INPUTOUTPUT ANOT A 01 10 Slide 25 Other gates NAND Not of ANAND NOR- Not of OR Slide 26 Xor Gate(4070) Truth Table(A B) INPUTOUTPUT ABA AND B 000 011 101 110 Slide 27 Multiplexer(MUX) And Demultiplexer(DeMux) Slide 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 Slide 29 Multiplexer Slide 30 Slide 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 Slide 32 What do we mean by Electrical? Slide 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 Slide 34 Demultiplexer Slide 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 Slide 36 Other considerations Electrical connection is not perfect Unconnected pins are left floating Slide 37 Problem Statement(Roulette) Slide 38 Slide 39 Extra features 2 Led at a Time Slide 40 Extra features Speed using LDR Slide 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/ Slide 42 Some rules Minimum 3 people per team, maximum 4 Maximum of 2 breadboards per team Slide 43 COMPONENTS ISSUE: 12TH AUGUST 8:00 PM TO 10:00 PM AT ELECTRONICS CLUB IN HALL 3 Slide 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 Slide 45 Slide 46 Thank You Website : students.iitk.ac.in/eclub Electrovate Website:- http://students.iitk.ac.in/eclub/electrovate/ http://students.iitk.ac.in/eclub/electrovate/ FB Group : www.facebook.com/eclub.iitk E-mail : [email protected]
