PROGRAM 2. ECO2 METER WITH ALARM
This program extends Program one, by making use of the buzzer and some fancy
user interface features, to make an alarm sound and the window turn red if a set
level of eCO2 is exceeded.
The slider at the bottom of the
window sets the eCO2 level at which
the buzzer should sound and the
window turn red. Try setting the
Alarm level a little higher than the
current eCO2 level and then breathe
on the sensor.
