Please take care, arduino A0 pin represent the analog input configured on #define pin - For this example this doesn't matter
You will connect your sensor to your external A2D Sensor
This example code is in the public domain.
Important:
1. Although it doesn't matter what pin you put in when initializing your MQ sensor function it is important that you don't
for any reason invoke the MQ.init() method because that method configures the selected pin as input and you may need it for

3. You must ensure that when invoking the setADC(value) method the value you are passing is within the expected parameters,
for example if it is a 10-bit ADC converter, we expect a value between 0 and 2^10 = 1024
