What you need

• HW-M10-2 3.3 V
• Arduino
• Pull-up resistor
• Connection cable

Steps

1. 1. Connect the potentiometer to the Arduino using the following pins: VCC to 3.3V, GND to GND, and a pin A0 to pin A0.
2. 2. Connect a pull-up resistor (10kΩ) between VCC and pin A0.
3. 3. Load the provided Arduino code.
4. 4. Connect your circuit to power.
5. 5. Try turning the potentiometer and observe the values change on the serial monitor.
6. 6. Check the datasheet for further details on specifications.
7. 7. Adapt the code for your project.
8. 8. Test your circuit.

Example code

```
int potVal;
void setup() {
  Serial.begin(9600);
}
void loop() {
  potVal = analogRead(A0);
  Serial.println(potVal);
}
```

Frequently asked questions

How to connect the potentiometer?
Connect VCC to 3.3V, GND to GND, and a pin A0 to pin A0 of the Arduino. Add a pull-up resistor (10kΩ) between VCC and pin A0.

Why is pin A0 necessary?
Pin A0 is an analog pin used to read the analog input of the potentiometer.

What values can the potentiometer take?
The HW-M10-2 3,3 V potentiometer can take values from 0 to 1023, corresponding to 1024 voltage levels between 0 and 3,3V.

Can I use a different potentiometer?
Check the datasheet for voltage values compatible with your Arduino.
