# Description
HTTP service to control monitor brightness.
# Requirements
* go 1.17.11
* ddcutil 1.2.2
* linux 5.13.16
# Build
``` shell
nix build
```
# Run
```
sudo result/bin/ddcutil-daemon
```
The `ddcutil` binary should run with root privileges, so we use `sudo`.

```shell
curl --request POST --data '{'value': 5}' 127.0.0.1:49281/set
```
Increase brightness:
```shell
curl --request POST --data '{"value": 5}' 127.0.0.1:49281/increase
```
Decrease brightness:
```shell
curl --request POST --data '{"value": 5}' 127.0.0.1:49281/decrease
```
