# UnicornHat
UnicornHat is a client library for [unicornd][unicornd]
```sh
$ go get github.com/JohnBrainard/unicornhat
```
## Example
```go
package main
import (
"log"
"math/rand"
"time"
"flag"
"github.com/JohnBrainard/UnicornHat"
)
func main() {
r := flag.Uint("r", 0, "red")
g := flag.Uint("g", 0, "green")
b := flag.Uint("b", 0, "blue")
clear := flag.Bool("clear", false, "clear display")
random := flag.Bool("random", false, "random")
flag.Parse()
client, err := unicornhat.Connect()
if err != nil {
log.Fatal(err)
}
if *random {
rand.Seed(time.Now().UnixNano())
pixels := [64]unicornhat.Color{}
for i := range pixels {
r := byte(rand.Float32() * 256)
g := byte(rand.Float32() * 256)
b := byte(rand.Float32() * 256)
pixels[i] = unicornhat.ColorNew(r, g, b)
client.SetAllPixels(pixels)
}
} else if *clear {
client.Clear()
} else {
pixels := [64]unicornhat.Color{}
for i := range pixels {
pixels[i] = unicornhat.ColorNew(
byte(*r),
byte(*g),
byte(*b),
)
}
client.SetAllPixels(pixels)
}
client.Show()
}
```
