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:

12:14 | We have also learnt to demonstrate:
