This manual teaches you how to master the USB connection with the PC.
Search for reference code on YouTube.
1. What’s on the board?
All the inputs and outputs are on the board.

2. Testing the board
Make a connection between the board and PC using the included USB cable. The LCD will display the message
“Press button SW3 ... SW7 to show analog input values SW8 to exit”. I n the meantime the LEDs will light up in sequence.
LD1 and LD2 are digital inputs.
Press each button and check the LCD readout to check if the board functions correctly.
Press button 1 ... 7 one after the other. When you press a button, the corresponding LED lights up, and the LCD
displays the corresponding value
Press button 1
Press button 2
Press button 3
Press this button to read the value of
potentiometer 1.
When you adjust the potentiometer, the
value on the display changes.
Potentiometer 1

5
Press button 4
Press this button to read the value of
potentiometer 2.
When you adjust the potentiometer, the
value on the display changes.
Press button 5
Press this button to read the temperature in
the room from the temperature sensor.
Press button 6
This shows you the value of the
temperature dependent resistor (NTC).
The resistance of this type of resistor
varies with the temperature.
When the temperature goes up, the value
of the resistor goes down.
Press button 7
This shows you the value of the light
dependent resistor (LDR).
If you cover the resistor the value will
change. More light will decrease the value
of the resistor.
This test shows us that the board is functional. The next test will show you how to communicate with the PC.

3. Testing the communication with the PC
Press button “8” to start the communication with the PC. The LCD shows the message “CONNECTING”. When the
connection has succeeded, the display indicates “USB CONNECTED”.
YOU MUST PRESS BUTTON 8 TO BE ABLE TO COMMUNICATE WITH THE PC!

We have 2 types of programs: a graphical demo and a Test & Diagnosis program.
1. Downloading the test programs
Download the software package from the EDU05 product page (www…..)
Graphical demo Test & Diagnosis
2. Installing the test programs
Extract the files in a folder on your drive. The folder “EDU05” and several subfolders will be created: C:\EDU05\
subfolder: \DLL\ contains the dynamic link library file EDU05.DLL. This file is required for every program, this file
must always be included. In your current projects folder, it can be handy to copy this file to your \windows\system32
folder.
\GraphicalDemo\ Contains the graphical demonstration and test program. See chapter 4.
\TestDiagnosis\Contains the test & diagnosis (numerical version) demonstration and test program.
\EDU05_VB2010_tutorial\ Step-by-step manual: how to make your first program in Visual Basic

The graphical demo reproduces an image of the board on your screen.
•First click the “Connect” button to connect the board with the software.
•Next, perform the same test as described in chapter 2 “Testing the board”. Because the board and the
PC communicate, you can see the exact same on your screen as while testing the board itself.

•You can click the buttons on the screen and see the result on the board.
 Remark: You need to press and hold the buttons on the board to see the result. The buttons on
the screen have a toggle function: click once to switch on, click again to switch off.

When you switch on the “Show binary value of button pressed” option, the PC screen and board will
indicate the binary value of the clicked button. In the example above button 5 was clicked.
•If all tests were successful, you can disconnect the board by clicking the “Disconnect” button. Then
continue with the next test.
(testing with the test & diagnosis demo).

This acts like a regulation of an output value. (1) changes the LCD
contrast, and (2) changes the LCD brightness.
