Pin Configuration

1M 3296W Trimpot (Pack of 5) Documentation
Overview
The 1M 3296W Trimpot is a single-turn cermet trimpotentiometer with a resistance value of 1 Megaohm. It is a variable resistor that allows for precise adjustments of resistance values. This trimpot is commonly used in electronic circuits for applications such as voltage division, signal attenuation, and impedance matching.
Pinout
The 1M 3296W Trimpot has three pins, which are explained below:
Pin 1: Counter-Clockwise (CCW) Terminal
Function: Connects to the wiper terminal internally
Description: This pin is connected to the counter-clockwise terminal of the trimpot. When the trimpot is turned counterclockwise, the resistance between this pin and the wiper terminal increases.
Pin 2: Wiper Terminal
Function: Moves along the resistance track as the trimpot is turned
Description: This pin is connected to the wiper terminal, which moves along the resistance track as the trimpot is turned. The wiper terminal connects to one of the end terminals (CCW or CW) depending on the trimpot's rotation.
Pin 3: Clockwise (CW) Terminal
Function: Connects to the wiper terminal internally
Description: This pin is connected to the clockwise terminal of the trimpot. When the trimpot is turned clockwise, the resistance between this pin and the wiper terminal decreases.
Connection Structure
To use the 1M 3296W Trimpot in a circuit, follow these steps:
1. Connect Pin 1 (CCW Terminal) to a fixed reference voltage: This can be a voltage source, ground, or any other fixed voltage point in the circuit.
2. Connect Pin 3 (CW Terminal) to another fixed reference voltage: This can be a different voltage source, ground, or any other fixed voltage point in the circuit. Ensure that the voltage difference between Pin 1 and Pin 3 is within the recommended operating range of the trimpot.
3. Connect Pin 2 (Wiper Terminal) to the load or signal path: This pin connects to the circuit or load that requires the variable resistance. The wiper terminal's resistance value changes as the trimpot is turned, allowing for precise adjustments to the circuit.
Important Notes
The trimpot should be used within its recommended operating voltage and current ratings to ensure reliable operation and prevent damage.
When turning the trimpot, avoid applying excessive force or torque, as this can damage the internal components.
To achieve precise adjustments, use a screwdriver or trim tool specifically designed for trimpots to avoid damaging the device.
By following these guidelines, you can effectively use the 1M 3296W Trimpot in your circuit to achieve precise resistance adjustments and optimized performance.

Code Examples

Here are three code examples demonstrating how to use the 1M 3296W Trimpot in various contexts:

Example 1: Voltage Divider (Arduino)

In this example, we'll use the Trimpot as a voltage divider to adjust the voltage level sent to an LED.

```c
const int potPin = A0; // Trimpot wiper connected to Analog Input 0
const int ledPin = 9; // LED connected to Digital Output 9

void setup() {

GPIO.setmode(GPIO.BCM)
pot_pin = 18
GPIO.setup(pot_pin, GPIO.IN)

while True:
  pot_value = GPIO.input(pot_pin)
  if pot_value:
    print("Resistor value adjusted to:", pot_value)
  time.sleep(0.1)
```

Example 3: Adjustable Threshold (ESP32 with MicroPython)

In this example, we'll use the Trimpot to adjust the threshold value for a simple light sensor circuit.

light_sensor = machine.Pin(33, machine.Pin.IN)

while True:
  pot_value = pot.value()
  light_level = light_sensor.value()
  if light_level > pot_value:
    print("Light level exceeded threshold!")
  time.sleep(0.1)
```
