This device can vary its resistance.
It can be used to adjust the volume or the brightness of a light.
Required Hardware
- Variable resistor (B10K used in this text)
- Arduino UNO
- UNO Cable
- Breadboard
- M-M Cable (3 pieces)
Connection
- Power is applied to the left and right, with the output coming from the middle.
- Power is applied to either the left or right, with the opposite terminal connected to GND.
- Connecting as described, turning to the right increases the value, but if connected oppositely (right to GND, left to 5V), turning to the left increases the value.
| Variable Resistor | Arduino UNO |
|---|---|
| Left | GND |
| Middle | A0 |
| Right | 5V |
Example Code
#define input A0
void setup()
{
// Start serial communication
Serial.begin(9600);
Serial.println("start");
Serial.println("======================");
}
void loop()
{
// Display the value of the variable resistor on the serial monitor
Serial.println(analogRead(input));
delay(1000);
}
