Features

• RV097GS Potentiometer
• Resistance: B50K
• Number of pins: 3+2 (five in total)
• Integrated switch

What it is for

RV097GS potentiometers are ideal for Arduino projects where continuous adjustment of variables such as volume or brightness is required. They can be used in applications that need continuous analog value adjustment and the use of an integrated switch.

Tutorial: How to use RV097GS Potentiometer with Switch

The RV097GS potentiometer is an extremely useful electronic component for continuously adjusting analog values. This dual potentiometer B50K with switch is ideal for Arduino projects, where it is used to control variables such as volume or brightness.

What you need

• Arduino Uno
• USB A-MicroB cable
• 3D Printing (for any enclosures)

Steps

1. Connect the potentiometer pins to the Arduino microcontroller: the middle pin to the ADC, and the two outer pins to GND and VCC.
2. Check the polarity of the connectors to avoid damaging the circuit.
3. Write a simple sketch on Arduino that reads the value of the potentiometer.
4. Use the switch as a switch to activate or deactivate functions in your project.
5. Test the project with an LCD display or LED to show the values adjusted by the potentiometer.

Example code

int potPin = A0; // pin analogico dove è collegato il potenziometro
void setup() {
  Serial.begin(9600);
}
void loop() {
  int potValue = analogRead(potPin);
  Serial.println(potValue);
}

Mini project

Create a light projector that changes intensity and color based on the position of the potentiometer. Use the switch to turn the projector on or off.

Common mistakes

• Connecting the pins in reverse, damaging the circuit.
• Not verifying the potentiometer resistance on the datasheet.
• Using an inappropriate ADC value to read the potentiometer.
• Not testing the switch before integrating it into the project.

Recommended accessories

• Arduino Uno
• 16×2 LCD Display with cable
• Variable RGB LED
• 330 ohm resistors

Frequently asked questions

Can the potentiometer be used with other microcontrollers?
Yes, but make sure to adapt the code and connections to the specific type of microcontroller.

How do you know which ADC to use for reading the potentiometer?
Check the datasheet of your Arduino or use the ADC closest to the potentiometer pins.
