# Controlling addressable LED strips based on the example of integration with the E-NODE AM-8.3 module
The purpose of this article is to present the method of controlling addressable LED strips using the example of integration with the E-NODE AM-8.3 module.
This integration allows for:
- Launching the programmed scene on the module
- Changing the brightness
To implement the example below we need:
- ***Gate HTTP ***(named ***HTTP***)
- module ***[E-NODE AM-8.3](http://www.sigma.net.pl/index.php?go=pok&id=15&tow=25&from=kat)***
- Addressable LED strip
Documentation for the E-NODE AM8.3 module can be found here
**Creating user features**
1\. Double-click on the ***HTTP*** object to enter the module settings:
2\. Go to the User Features tab and create the features you need:
- ***SelectedProgram*** - Initial value: ***0*** Type: ***number***
- ***Brightness*** - Initial value: ***255*** Type: ***number***
****
***Configuration of virtual objects***
1\. On the ***Gate HTTP*** module, we add the ***HttpRequest*** virtual object:
2\. Enter the name of the object: ***ChangingBrightness\_Request*** and complete the values of the embedded features of the object:
**Host:** http://192.168.0.222 (converter IP address)
**Path:** /Player?4?254
3\. On the ***HTTP Gate*** module, we add another ***HttpRequest*** virtual object:
4\. Enter the name of the object: ***ModeSelection\_Request*** and complete the values of the embedded features of the object:
***Host*:** http://192.168.0.222 (converter IP address)
***Path*:** /Player?2?3
5\. On the ***HTTP Gate*** module, we add another ***HttpRequest*** virtual object:
6\. Enter the name of the object: ***ReadStatus*** and complete the values of the embedded features of the object:
***Host***: http://192.168.0.222 (converter IP address)
***Path***: /Player?1
7\. We add the ***Timer*** virtual object to the ***Gate HTTP*** module:
8\. Enter the name of the object: ***TimerDelay*** and complete the values of the embedded features of the object:
**Creating scripts**
1\. Add the ***sModeSelection*** script
Add a script parameter with the name ***program*** and type ***number***
Paste the following script content:
```
local path = "/Player?2?" .. program HTTP->ModeSelection_Request->SetPath(path)HTTP->ModeSelection_Request->SendRequest()
```
2\. Add the ***sChangeBrightness*** script
Add a script parameter named **brightness** and type **number**
Paste the following script content:
```
local path = "/Player?4?" .. brightnessHTTP->ChangingBrightness_Request->SetPath(path)HTTP->ChangingBrightness_Request->SendRequest()
```
3\. Add the **sReadStatus** script
Wklej poniższą treść skryptu:
```
local data = HTTP->ReadStatus->ResponseBodyHTTP->SelectedProgram = string.match(data, "%d+")HTTP->Brightness = string.match(data, "%,(%d+)")
```
**Assigning scripts to objects**
1\. Assign the ***Start()*** method of the ***TimerDelay*** virtual object to the ***OnResponse*** event of the ***ModeSelection\_Request*** object:
2\. Assign the **Start()** method of the ***TimerDelay*** virtual object to the ***OnResponse*** event of the ***BrightnessChange\_Request*** object:
3\. Assign the ***sReadState()*** script to the ***OnResponse*** event of the ***ReadState*** object.
4\. Assign the ***SendRequest()*** method of the ***ReadState*** virtual object to the ***OnTimer*** event of the ***TimerDelay*** object:
**Module control**
To turn on the programmed scene, call the ***sModeSelection*** script with a parameter specifying the program number. This can be done, for example, using the scene widget. This widget should be configured as follows:
Thanks to this configuration, we can run the program previously saved on the module.
To control the brightness, call the ***sChangeBrightness*** script with the parameter value you want to set. This can be done, for example, via the slider widget. This widget should be configured as follows:
