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
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
n the meantime the LEDs will light up in sequence.
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.

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 button 6
Potentiometer 2
Press this button to read the temperature in
the room from the temperature sensor.
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 test shows us that the board is functional. The next test will show you how to communicate with the PC.
EDU05 Test procedure & programming in Visual Basic 2010 ( Version 1.0)
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.
