1. The Intel Galileo Gen 2 board provides the following resolution for the analog to digital converter:

   1. 32 bits.

   2. 64 bits.

   3. 12 bits.

2. The analog pins allow us to detect a maximum of:

   1. 4,096 different values, with values ranging from 0 to 4095 (inclusive).

   2. 16,384 different values, with values ranging from 0 to 16,383 (inclusive).

   3. 256 different values, with values ranging from 0 to 255 (inclusive).

3. We can configure the number of bits we want to use as the resolution by calling the following method of an mraa.Aio instance:

   1. setADCResolution.

   2. setBit.

   3. setResolutionBits.

4. A call to the read method for a mraa.Aio instance returns:

   1. A raw number of units based on the number of the resolution bits configured for the instance.

   2. A voltage value automatically converted from the raw number of units.

   3. A resistance value measured in Ohms (Ω).

5. We can use analog pins to read:

   1. Resistance values.

   2. Current values.

   3. Voltage values.
