The `acer_projector` switch platform allows you to control the state of RS232 connected projectors from [Acer](http://www.acer.com).

```yaml
# Example configuration.yaml entry
switch:
  platform: acer_projector
  filename: /dev/ttyUSB0
  name: Projector
  timeout: 1
  write_timeout: 1
```

Configuration variables:

- **filename** (*Required*): The pipe where the projector is connected to
- **name** (*Optional*): The name to use when displaying this switch.
- **timeout** (*Optional*): Timeout for the connection in seconds.
- **write_timeout** (*Optional*): Write timeout in seconds.
