Mustang LEDS

Using an Arduino to interface with the RoboRIO over and Ethernet shield and receive commands for color changing LEDs. Sample animations can be found in the folder.

Parts List

• RoboRIO
• Arduino with Ethernet. This can be an Arduino with an Ethernet shield, or something like the Yun which has it built in
• Neopixel strip (WS2812 Integrated Light Source)
• Ethernet switch for extra Ethernet ports, so you can use Ethernet on RoboRio both for all your necessities and the fancy lights too

Setting up for your team / Code checklist

Neopixels connected to Arduino pin 6. Using RGB format at 800KHZ bitstream

• Pin 6 on Arduino/Ethernet shield to white wire (DATAIN) on Neopixel strip
• 5v pin on Arduino/Ethernet shield to red wire (VIN) on Neopixel strip
• GND pin on Arduino/Ethernet shield to black wire (GND) on Neopixel strip
• Arduino Ethernet shield to robot radio (as long as it's somehow connected to Ethernet on the robot side)
• Arduino to USB power

In the Arduino code, to set up IP addresses:

IPAddress ip(10,te,am,3);                            //Defines a static IP for the Arduino/Ethernet Shield.
                                                     // For example: 10,6,70 for ours
IPAddress robotIp(10,te,am,2);                       //Defines the robot's IP

...
    
robotClient.connect(robotIp, 5801);               //Connects the client instance to the robot's socket at 5801;

On the RIO-side, make sure you have this in robotInit:

 public void robotInit() {
    ...
    leds.socketSetup(5801);
    ...
  }

To run on RIO, deploy robotside code with gradle ./gradlew deploy and also upload the Arduino sketch to the Arduino.
