unsigned int littleWire::analogRead

(

unsigned char

channel

)

Read analog voltage. Analog voltage reading from ADC_PIN3 isn't advised (it is a bit noisy) but supported. Use it at your own risk.
For more about internal temperature sensor, look at the Attiny85 datasheet.

Parameters:

channel

Source of ADC reading (ADC_PIN2 , ADC_PIN3 or ADC_TEMP_SENS)

Returns:

10 bit ADC result with reference to 5V
