This package provides drivers for [i2c ](https://en.wikipedia.org/wiki/I%C2%B2C )devices. It must be used along with an adaptor such as [firmata ](https://gobot.io/x/gobot/platforms/firmata ) that supports the needed interfaces for i2c devices.

## Using A Different Bus or Address
You can set a different I2C address or I2C bus than the default when initializing your I2C drivers by using optional parameters. Here is an example:
```go
blinkm := i2c.NewBlinkMDriver(e, i2c.WithBus(0), i2c.WithAddress(0x09))
```
