You can use this sensor to detect the air quality. Press
Ctrl
+
C
to quit.
Notice
You may have noticed that for the analog port, the silkscreen pin number is something like
A1, A0
, however in the command we use
parameter
0
and
1
, just the same as digital port. So please make sure you plug the module into the correct port, otherwise there may be pin
conflicts.
I2C
We will take the
Grove - OLED Display 128x64
for example to introduce the I2C port.
