[vc_row][vc_column width=”1/1″][vc_column_text]This is a handy potentiometer breakout that can be used to adjust signal level in robotics.
There are three pins: power supply, voltage, signal.

We use the included Arduino IDE in pcDuino:
Code:
#include <core.h>
const int analogInPin =0;
int sensorValue = 0; // value read from the pot
int count1;
void setup() {
}
void loop() {
count1++;
// read the analog in value:
sensorValue = analogRead(analogInPin);
if(count1==3000)
{
count1=0;
printf(“sensor=%d\n”, sensorValue);
}
}

Click the left-point arrow to run the code on pcDuino, the reading changes when we adjust the potentiometer.
