class ADC

Example

# Import ADC class
from robot_hat import ADC

# Create ADC object with numeric pin numbering
a0 = ADC(0)
# Create ADC object with named pin numbering
a1 = ADC('A1')

# Read ADC value
value0 = a0.read()
value1 = a1.read()
voltage0 = a0.read_voltage()
voltage1 = a1.read_voltage()
print(f"ADC 0 value: {value0}")
print(f"ADC 1 value: {value1}")
print(f"ADC 0 voltage: {voltage0}")
print(f"ADC 1 voltage: {voltage1}")
