Switch describes a touch sensor. A Switch instance contains the following attributes:
Table A.5. Switch's attributes:
| Name | Description |
|---|---|
| val | The switch status (0 or 1). |
| port | The port where the servo is plugged. It can be 1, 2, 3 or 4. You can change the value while the server is running. Beware, if you change the port, that will free the old port (so you will be able to create another device on it) and will busy the new one (so you won't be able to create another device on it). |
| init(port_) | The UObject constructor.
Example: bumper = new Switch(1); |
