2 Pieces RV097GS 3 + 2 Potentiometer B20K with Switch

Description

What it is

The RV097GS pieces are double B20K potentiometers with a switch, useful for adjusting analog values in electronic projects such as those based on Arduino. This component is ideal for both beginners and experts in the creation of various types of DIY devices.

Features

• 2 pieces RV097GS double B20K potentiometer with switch
• Designed for precise adjustments in Arduino and DIY projects

What it is for

The RV097GS can be used to create a dimmer for an LED lamp. By connecting the potentiometers to two analog pins of the Arduino and the switch to the GND pin, the brightness can be controlled flexibly.

Tutorial: How to use RV097GS Double B20K Potentiometer with Switch

The RV097GS potentiometer is an extremely useful electronic component for Arduino projects, allowing for continuous adjustment of the analog value. Ideal for both beginners and more experienced makers.

What you need

• Arduino Uno/Nano
• USB Cable
• 3D Printing (optional)
• Connect to PC

Steps

1. Connect the potentiometer to pins A0, A1, and GND of the Arduino using wires.
2. Verify the correct circuit connection with a multimeter or by checking the digital output in Serial Monitor.
3. Write an Arduino sketch to read the value of the potentiometer.
4. Insert and verify the function of the switch connected to the GND pin.
5. Test the entire circuit by adjusting the two potentiometers and pressing the switch.

Example code

int valA0 = 0;
int valA1 = 0;
void setup() {
Serial.begin(9600);
pinMode(A0, INPUT);
pinMode(A1, INPUT);
}

void loop() {
valA0 = analogRead(A0);
valA1 = analogRead(A1);
Serial.print(valA0);
Serial.print(", ");
Serial.println(valA1);
delay(500);}

Mini project
