The document describes the Super Probe, a multi-functional electronics testing device. The Super Probe can perform 10 functions including logic probing, IR testing, voltage measurement, capacitance measurement, diode checking, frequency counting, PWM signal generation, general signal generation, logic pulsing, and square wave generation. It uses a PIC microcontroller and simple switches and display to control and output measurements in a compact and low-cost device. The Super Probe was created to reduce complexity when performing electronics experiments using minimal hardware.

6. 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

7. 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

10. 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 38
USED FOR TESTING IR RECIEVER MODULES
GENERATE 1ms ON AND 2.5 ms OFF OF 38KHZ SQUARE WAVE

11. VOLT METER
 FOR VOLTAGE MEASUREMENT
 MEASURES 0-5V RANGE
CAPACITANCE MEASUREMENT
 MEASURES THE CAPACITANCE VALUE
 RANGE OF MEASUREMNT IS 0.001 TO 500UF.

12. DIODE CHECKER
 CHECK WHETHER THE DIODE IS GOOD OR BAD
FREQUENCY COUNTER
 TO MEASURE THE GIVEN FREQUENCY UP TO 50 MHz
super probe 12

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

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

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

17. 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 .

18. CONCLUSION
 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?
