oSimilarly, you can use the slide potentiometer to vary the speed of your Mini
Fan or the frequency with which your Grove - Buzzer module sounds
oThe slide potentiometer can also be used as an ON/OFF switch for any circuit.
Take the slider to the Vcc position to switch it ON and move it down to GND to
switch OFF a circuit.
In terms of choosing a power module, you can use either the Grove - USB
Power module or the Grove - DC Jack Powermodule for building standalone Grove
circuits.
With Arduino
As a Voltage Divider
Follow these simple steps to make the slide potentiometer module function as a
voltage divider:
1. When using the module in conjunction with an Arduino or a Seeeduino, use
the Grove - Base Shield and connect the Grove - Slide Potentiometer module
to the shield using a designated Grove Interface (e.g., Analog Port 0 as shown
below):
2. Connect the board to PC using USB cable
3. Upload the following sample sketch:
int adcPin = A0; // select the input pin for the potentiometer
int ledPin = A1; // select the pin for the LED
int adcIn = 0;// variable to store the value coming from the sensor
void setup()
{
Serial.begin(9600); // init serial to 9600b/s
pinMode(ledPin, OUTPUT); // set ledPin to OUTPUT
Serial.println("Sliding Potentiometer Test Code!!");
}
void loop()
{
// read the value from the sensor:
