KeyboardInterrupt
When you change the distance between the Grove - Ultrasonic Ranger and the target object, the measurment value will change accordingly.
Press Ctrl+Cto quit.
Attention
For most grove module, you need to add the pin number parameter, like grove_ultrasonic_ranger 5 6, 5and 6are the
GPIO/BCM pin. However, you may have noticed that in the first example grove_pwm_buzzer, we didn't add a parameter after the
command. This is because the PWM port and I2C port do not require pin number parameters. You can find the pin number silkscreen just
besides the Grove sokect.
Analog Port
We will take the Grove - Air quality sensor v1.3 for example to introduce the Analog port.
Hardware connection diagram
Tap the following command grove_air_quality_sensor_v1_3 0 1 in the command line interface.
