## How to wire

The module has 16 pins.

* **VSS** - GND
* **VDD** - +5V
* **V0** - >500 ohm resistor, connected to GND
* **RS** - Any available GPIO pin
* **RW** - GND
* **E** - Any available GPIO pin
* **D0** - Leave disconnected
* **D1** - Leave disconnected
* **D2** - Leave disconnected
* **D3** - Leave disconnected
* **D4** - Any available GPIO pin
* **D5** - Any available GPIO pin
* **D6** - Any available GPIO pin
* **D7** - Any available GPIO pin
* **A** - >500 ohm resistor, connected to +5V
* **K** - GND

## Using the driver

Instantiate the driver using the static `make()` function, passing a reference to each pin.

```php theme={null}
use DanJohnson95\Pinout\Facades\PinService;
use DanJohnson95\Pinout\Drivers\LCD1602;

$driver = LCD1602::make(
    readSelect: PinService::pin(13), // RS pin
    enable: PinService::pin(14), // E pin
    data4: PinService::pin(15),
    data5: PinService::pin(16),
    data6: PinService::pin(17),
    data7: PinService::pin(18),
);
```

You can call the following methods on the driver:

### Available methods

#### `home`

Moves the cursor to the beginning of the first line.

#### `shiftLeft`

Moves the cursor one position to the left

#### `shiftRight`
