### Blink LED with periph in Go

Source: https://github.com/periph/host/blob/main/README.md

This Go code snippet demonstrates how to blink an LED connected to a Raspberry Pi using the periph library. It initializes the host, sets up a ticker for timing, and toggles the state of a GPIO pin (P1_33) to create a blinking effect.

```Go
package main

import (
    "time"
    "periph.io/x/conn/v3/gpio"
    "periph.io/x/host/v3"
    "periph.io/x/host/v3/rpi"
)

func main() {
    host.Init()
    t := time.NewTicker(500 * time.Millisecond)
    for l := gpio.Low; ; l = !l {
        rpi.P1_33.Out(l)
        <-t.C
    }
}
```
