PROJECT OVERVIEW

COMPLEXITY WHILE DOING AN EXPERIMENT ......

HOW TO REDUCE THE COMPLEXITY ?

CHALLENGE OF USING MINIMUM HARDWARE TO PRODUCE MAXIMUM OUTPUT. CAME WITH THE IDEA SUPER PROBE.

SIMPLE DEVICE WITH MULTIFUNCTION

10 FUNCTIONS

1. LOGIC PROBE

2. IR 38

3. VOLTMETER

4. CAPACITANCE MEASUREMENT

5. DIODE CHECKER

6. FREQUENCY COUNTER

7. PWM

8. SIGNAL GENERATOR

9. LOGIC PULSER

10. SQUARE WAVE GENERATOR

Microcontroller Unit:

It is a Special purpose microprocessor with built in memory

It can be programmed according to the purpose

Here we uses a Peripheral Interface Controller PIC 16F873A

It has 3 bidirectional ports as inputs and outputs

It process the given data and generates the required output as per the

program

The DISPLY connected to the output ports of the microcontroller

SWITCHES

OPERATION IS VIA TWO PUSH BUTTON SWITCHES.

HOLDING DOWN BUTTON NUMBER 2 WHILE PUSHING

BUTTON

NUMBER 1 CYCLES THROUGH OPERATING MODES.

SEVEN SEGMENT DISPLAY 4 SEVEN SEGMENT DISPLAYS ARE USED

POWER SUPPLYCONTROLLER NEED 5V SUPPLY

REGULATOR IS USED FOR MAINTAING THE 5V

10super probe

LOGIC PROBE

USED FOR THE ERROR DETECTION OF LOGIC CIRCUIT

IT DISPLY S H FOR HIGH , L FOR LOW, “_” FOR TRISTATE AND P FOR PULSE

IR 38USED FOR TESTING IR RECIEVER MODULES

GENERATE 1ms ON AND 2.5 ms OFF OF 38KHZ SQUARE WAVE

11super probe

VOLT METER FOR VOLTAGE MEASUREMENT MEASURES 0-5V RANGE

CAPACITANCE MEASUREMENT MEASURES THE CAPACITANCE VALUE

RANGE OF MEASUREMNT IS 0.001 TO 500UF.

12super probe

DIODE CHECKER CHECK WHETHER THE DIODE IS GOOD OR BAD

FREQUENCY COUNTER

TO MEASURE THE GIVEN FREQUENCY UP TO 50 MHz

super probe 13

PWM GENERATE VARIABLE PULSE WIDTH 3-97% OF 6K Hz SIGNAL

SWITCH 1 DECREASES PULSE WIDTH AND SWITCH2 FOR

INCREASING THE WIDTH

SIGNAL GENERATOR IT GENERATES A 500Hz SQUIRE WAVE AT ABOUT 0.5V

THE SIGNAL IS GENERATED WHILE SWITCH 1 IS HELD DOWN

super probe 14

LOGIC PULSER CHECK THE LOGIC CIRCUITS.

IT GENERATES PULSE RATE _5,50,500 AND 5K

SQUARE WAVE GENERATOR

GENERATE SQUARE WAVE

THE RANGE IS 1-9999Hz

SOFTWARE

The program is prepared in assembly language and developed using assembler PIC. The IC burned using the software IC PROG

FLOW CHART

ADVANTAGES & SCOPES

REDUCE THE COMPLEXITY

EFFICIENT TOOL FOR MULTIPURPOSES

THE SYSTEM IS VERY MUCH COMPACT & ECONOMICAL

INCRESE THE NUMBER OF FUNCTIONS WITH SLIGHT MODIFICATION IN THE SOFTWERE .

CONCLUSION

18super probe

THE PROBLEMS AND COMPLEXITY ARISES IN THE LABS ARE INEVITABLE BUT WE CAN REDUCE IT.

WE DESIGNED THIS AS A REMEDY FOR THIS.

WHY WE DID NOT USE SUPPER PROBE IN OUR LABS?
