+## Example
+
+Blink a LED:
+
+~~~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
+    }
+}
