Here are two examples:
1. This LED should be glowing Red when "on" and just turn off when "off".
The Setting in ARduino is:
int DledOnColors[DLEDcount][3] = {
{255,0,0}
};
The Setting in Arduino is:
```int DledOnColors[DLEDcount][3] = {{255,0,0}};```
int DledOffColors[DLEDcount][3] = {
{0,0,0}
};
```int DledOffColors[DLEDcount][3] = {{0,0,0}};```
2. This LED should glow Green when "on" and Red when "off".
int DledOnColors[DLEDcount][3] = {
{0,255,0}
};
```int DledOnColors[DLEDcount][3] = {{0,255,0}};```
int DledOffColors[DLEDcount][3] = {
{255,0,0}
};
```int DledOffColors[DLEDcount][3] = {{255,0,0}};```
Easy right?
# latching Potentiometers
This is a special Feature for rotary Selector Switches. Instead of loosing one Pin per Selection you can turn your Switch in a Potentiometer by soldering 10K resistors between the Pins and connecting the Selector Pin to an Analog Input.

The Send and receive Protocol is <Signal><PinNumber>:<Pin State>
To begin Transmitting Ready is send out and expects to receive E: to establish connection. Afterwards Data is exchanged.
Data is only send everythime it changes once.

Command 'E0:0' is used for connectivity checks and is send every 5 seconds as keep alive signal. If connection is lost the arduino begins flashing an LED to alarm the User.
Command 'E0:0' is used for connectivity checks and is send every 5 seconds as keep alive signal. If it is not received in Time, the connection is lost and the arduino begins flashing an LED to alarm the User. It will however work the same and try to send it's Data to the Host.
