Slide Potentiometer Module

It's a component capable of varying resistance values. It can be used for adjusting volume or the brightness of light.

Specifications

• Recommended Input Voltage: 3.3V ~ 5V
• Two analog output pins (output values are the same for both pins)
• 10Kohm

Example Required Hardware

• Arduino board
• Jumper cables
• Slide potentiometer module
• LCD1602

Connection

Arduino	Slide Potentiometer Module	LCD
5V	VCC, VCC	VCC
GND	GND, GND	GND
A4		SDA
A5		SCL
A6	OTB
A7	OTA

Example Code

This example demonstrates how to display the values from the slide potentiometer on an LCD screen.

Please refer to the link for instructions on using the LCD.

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);

const int otb = A6;
const int ota = A7;
int val1 = 0;
int val2 = 0;

void setup() {
  lcd.init();
  lcd.backlight();
  lcd.setCursor(0, 0);
  lcd.print("OTA:");
  lcd.setCursor(0, 1);
  lcd.print("OTB:");
}

void loop() {
  if (val1 != analogRead(ota)) {
    val1 = analogRead(ota);
    for (int i = 4; i < 8; i++) {
      lcd.setCursor(i, 0);
      lcd.print("    ");
    }
    lcd.setCursor(4, 0);
    lcd.print(val1);
  }

  if (val2 != analogRead(otb)) {
    val2 = analogRead(otb);
    for (int i = 4; i < 8; i++) {
      lcd.setCursor(i, 1);
      lcd.print("    ");
    }
    lcd.setCursor(4, 1);
    lcd.print(val2);
  }
  delay(300);
