|-
|00:07
|In this tutorial, we will learn about:

* Various terminals on the Panel

* Software interface.

|-
|00:17
|We will also learn to demonstrate:

* Ohm's law

* Effective resistance in parallel combination and

* Show the circuit diagrams of our experiments.

|-
|00:33
|Here I am using,

* '''ExpEYES''' version 3.1.0

* '''Ubuntu Linux''' OS version 14.04

|-
|00:43
|To follow this tutorial, you should be familiar with:
*'''ExpEYES Junior''' interface.If not
*for relevant tutorials, please visit our website.

|-
|00:55
|Let's discuss about the utilities of '''ExpEYES Junior device'''.

|-
|01:00
|Device can be used to carry out experiments in:

* Higher Secondary

* Undergraduates

* Electrical and

* Electronics Engineering courses.

|-
|01:12
|It can be used in fields such as:
* Electricity

* Sound

* Magnetism

* Light

* Diode

* Transistors and others.

|-
|01:23
|Let's begin with terminals on the top '''Panel'''.'''Panel''' has four ground ('''GND''') terminals.At these terminals the voltage is '''zero''' '''volt'''('''0V''').

|-
|01:35
|Voltage measured at other input terminals, is with reference to ground('''GND''') terminals.

|-
|01:42
|Input terminals '''A1''' and '''A2''' can measure voltage between '''-5V to +5V'''.

|-
|01:51
|On the left, '''IN1''' and '''IN2''' terminals can measure voltage between '''0 to 5V'''.

|-
|01:59
|''''IN1''' also measures capacitance up to '''5000pF(pico farads)''', with good accuracy.

|-
|02:07
|'''PVS''' is '''Programmable voltage source'''.
It is used to deliver voltages *in '''0-5V''' range
*with a minimum step of '''1.25mV(milli volts)'''and can deliver up to '''5mA(milli amps)'''.

|-
|02:25
|'''SINE''' delivers a constant frequency around '''150 Hz''', at an amplitude around 4volts.

|-
|02:33
|'''SEN''' is mainly used for connective sensor elements like
*'''photo-transistors''',
*'''Light Dependent Resistors''',
*'''Thermistors''' etc.

|-
|02:45
|It is a voltage measuring terminal with an internal '''5.1k''' resistor connected to 5 volts.

|-
|02:52
|'''SQR1''' and '''SQR2''' terminals can generate
*'''Square waves''' of “0” to “5V”
*with a frequency from '''0.7 Hertz''' to '''100 Kilo Hertz'''.

|-
|03:05
|'''OD1''' produces a digital output as '''0V''' or '''5V''', under Software control.

|-
|03:13
|'''MIC''' captures sound from an external sound source.

|-
|03:18
|'''CCS''' means '''Constant Current Source'''.

|-
|03:22
|It gives
*'''1mA'''('''one milli Amps''') current
*with a load resistor of '''3kΩ'''(kilo ohms), since voltage should be kept below '''4 volts'''.

|-
|03:31
|'''Inverting amplifier''' is used to amplify external voltages. It may be used to amplify external '''condenser''' or '''mic''' output.

|-
|03:42
|Along with the device some accessories are provided

|-
|03:47
|Accessories list include:

* Two '''Piezo Electric Discs'''

* Two 3000 turns coils

* DC Motor

|-
|03:56
|
* Screwdriver

* Set of four permanent Magnets

* Four Crocodile Clips with wires

* '''Transistor'''

|-
|04:05
|* Two '''silicon diodes'''

* '''LDR & Thermistor'''

* '''Capacitors'''

|-
|04:12
|* Four 5mm '''LEDS'''

* Four wires

* '''Resistors'''.

|-
|04:19
|This is a graphical user interface(GUI) of '''ExpEYES Junior'''. GUI is known as '''Plot window'''.

|-
|04:28
|On the left side of the '''Plot window''', we have input terminals:'''A1, A2, IN1, IN2, SEN, SQ1 and SQ2'''.

|-
|04:40
|'''ATR, WHI''' and others '''trigger sources''' are used to fix the waveform.

|-
|04:48
|We will discuss about '''ATR, WHI''' and others '''trigger sources''' in the upcoming tutorials.

|-
|04:56
|'''CH1, CH2, CH3, CH4''' are plotting channels with sliders.

|-
|05:04
|Channel sliders on the right are used to move the wave form on the '''Plot Window'''.

|-
|05:11
|Click on '''A1''' and drag to '''CH1'''. We can see the connection information in the box below.

|-
|05:21
|Click on '''A2''' and drag to '''CH2'''.We can see the connection information as before.

|-
|05:29
|Drag channel '''CH2''' to '''FIT'''.It shows the voltage and frequency of '''A2'''.

|-
|05:38
|Drag '''CH2''' to '''NML'''.It removes the display shown by '''FIT'''.

|-
|05:44
|'''msec/div'''('''milli second/division''') represents time axis.

|-
|05:51
|'''Volt/div''' represents volt axis.

|-
|05:56
|'''Trig level''' is a '''trigger''' controller.

|-
|06:00
|Click on '''CH2''' and drag to '''DEL'''. It removes '''CH2'''.

|-
|06:07
|Click on '''CH1''' and drag to '''DEL'''.It disables the display of '''CH1'''.

|-
|06:15
|'''FTR''' generates '''Fourier spectrum''' of the wave.

|-
|06:20
|Under '''Setting Squarewaves''' we have a number of input and check boxes.

|-
|06:26
|In this '''input box''' we can change the Frequency of the wave in '''Hertz''',

|-
|06:33
|This is to change '''phase difference, dphi''' in percentage(%).

|-
|06:38
|In '''Set PVS=''' input box. we can enter the desired voltage value between '''0''' to '''5V'''.Press '''Enter''' to set the value.

|-
|06:52
|'''SQR1, SQR2''' and '''BOTH''' check boxes are used to activate the frequency.Frequency can be changed using the slider.

|-
|07:04
|'''Set State''' check boxes are used to control '''OD1''' and '''CCS'''.

|-
|07:11
|'''Measure C on IN1''' button is used to measure '''Capacitance'''.'''

|-
|07:16
|Measure R on SEN''' button is used to measure '''Resistance'''

|-
|07:21
|Below the buttons we have a command window to type '''Python''' code.We will discuss about '''Python''' code in upcoming tutorials.

|-
|07:31
|'''Save Traces to''' button to save traces as '''.txt''' files

|-
|07:37
|We will discuss about '''LOOP''' check box, '''SCAN''' and '''XMG''' buttons in later tutorials.

|-
|07:45
|'''EXPERIMENTS''' button displays list of experiments.'''Quit''' button is used to close the window.

|-
|07:53
|Now I will demonstrate '''Ohm's''' law using the device and its interface.

|-
|07:59
|In this experiment we will show:

* The dependency of voltage across a resistor and

* Verify '''Ohm’s law'''

|-
|08:09
|The device is connected to the system.

|-
|08:12
| In this experiment '''PVS''' is connected to '''IN1''' through '''2.2KΩ'''('''kilo ohms''') resistance.'''IN1''' is connected to ground('''GND''') through '''1KΩ'''('''kilo ohms''').

|-
|08:25
|This is the circuit diagram for the connection.

|-
|08:30
|Open the software interface.

|-
|08:32
|In the Plot window click on '''IN1''' to measure the voltage.

|-
|08:37
|For '''PVS=1 Volt''', the corresponding value of '''IN1''' is '''0.309 Volt'''.
For '''PVS=2V''', '''IN1''' value is '''0.619V'''
For '''PVS=3V''', '''IN1''' value is '''0.928V'''.

|-
|09:01
|As an assignment,

* Change '''PVS''' values from 0 to 5 volts and

* Check the corresponding '''IN1''' values.

|-
|09:10
|Let us perform an experiment to check the effective resistance in series combination.

|-
|09:16
| In this experiment we will show the voltage when resistors are connected in series.

|-
|09:23
|In this experiment
*'''IN1''' is connected to '''CCS'''
*'''CCS''' is connected to ground through a resistor

|-
|09:33
|On the '''Plot window''' select the '''CCS''' check box. Click on '''IN1''' to show the voltage.

|-
|09:42
|This is the circuit diagram for the connection.

|-
|09:45
|When '''1 KΩ'''(kilo ohms) resistor is connected to '''CCS''' and '''GND''', measured voltage is '''0.979V'''.

|-
|09:54
|Likewise, for '''560 Ω'''(ohms) resistance, measured voltage is '''0.543V'''.

|-
|10:02
|For a series combination of '''1 KΩ''' (kilo ohms)and '''560Ω'''(ohms) resistances, measured voltage is '''1.524V''''.

|-
|10:14
|Let us perform an experiment to check the effective resistance in parallel combination

|-
|10:21
|In this experiment we will show the voltage when resistors are connected in parallel.

|-
|10:28
|In this experiment '''IN1''' is connected to '''CCS'''. '''CCS''' is connected to ground('''GND''') through a resistor.

|-
|10:38
|This is the circuit diagram for the connection.

|-
|10:40
|On the '''Plot window''' select the '''CCS''' check box. Click on '''IN1''' to show the voltage.

|-
|10:49
|The experiment is first carried out with '''1000Ω'''(ohms) resistor then with parallel combination of two '''1000 Ω'''(ohms) resistors.

|-
|11:01
|This is the circuit diagram for '''1000 Ω'''(ohm) resistance in parallel combination. The measured value of IN1 is '''0.952V'''.

|-
|11:11
|This is the circuit diagram for parallel combination of two '''1000 Ω'''(ohm) resistors.The measured value of '''IN1 is 0.474V'''.

|-
|11:25
|Again the experiment is carried out
*first with '''2.2K Ω'''(kilo ohms) resistor
*then with parallel combination of two '''2.2 KΩ'''(kilo ohms) resistors

|-
|11:38
|This is the circuit diagram for '''2.2K Ω'''(kilo ohms), resistance.The measured value of '''IN1''' is '''2.132V'''

|-
|11:48
|This is the circuit diagram for parallel combination of two '''2.2KΩ'''(kilo ohms) resistance.The measured value of '''IN1 is 1.063V'''
