Manufacturer: seeed
Connection: analog

This class is being replaced by the upm-slide library and the Slide class.

Basic UPM module for the Grove slide potentiometer on analog that returns either a raw value or a scaled voltage value.

    upm::GroveSlide* slide = new upm::GroveSlide(0);    // Instantiate new grove slide potentiometer on analog pin A0
    cout << slide->name() << endl;
    while(true) {
        float adc_value = slide->raw_value();       // Read raw value
        float volts = slide->voltage_value();    // Read voltage, board reference set at 5.0V
        fprintf(stdout, "%4d = %.2f V\n", (uint16_t)adc_value, volts);
        usleep(2500000);    // Sleep for 2.5s
    }
