### Examples

```python

at42 = at42qt2120.AT42QT2120(i2c, at42_change_pin)

# Detect of any keys are touched

if at42.change_detected():

    print('Touch detected')

# Enable slider or wheel mode. Position is between 0-255

at42.enable_slider()

print(at42.get_slider_wheel_position())

# Get detection signal from key 3. Result is between 0-65535

at42.get_key_signal(3)

```
