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.
