Time Narration
00:01 Hello everyone. Welcome to this tutorial on Panel connections and Software interface.
00:07 In this tutorial, we will learn about:

Various terminals on the Panel Accessory set and Software interface.

00:17 We will also learn to demonstrate:

Ohm's law

Effective resistance in series combination

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 The 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 of Panel. Panel has four ground (GND) terminals. At these terminals, the voltage is zero volt (0 V).
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 5000 pF(pico farads), with good accuracy.
02:07 PVS is Programmable voltage source. It is used to deliver voltages in 0-5 Volts range with a minimum step of 1.25 mV (milli volts) and can deliver up to 5 mA (milli amps).
02:25 SINE delivers a constant frequency around 150 Hz, at an amplitude around 4 volts.
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 1 mA(one milli Amp) current with a load resistor of 3 kΩ(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 includes:

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 other trigger sources are used to fix the waveform.
04:48 We will discuss about ATR, WHI and other 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 waveform 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 2.2 KΩ (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.
12:03 Let's summarize.
12:05 In this tutorial, we have learnt:

Various terminals on the panel Accessory set and Software interface.

12:14 We have also learnt to demonstrate:
