Question

I am trying cause my Arduino UNO to trigger the recording of Video through the Save Video Module in Jevois and save it on the SD card in the Camera. I want to trigger the start of recording and the end of recording using a button that I press on my Arduino UNO. Copied below is the code I am using. It is displaying the message in the Arduino Serial Monitor but it is not triggering the camera to begin recording or stop recording.

#define rxPin 0
#define txPin 1
#define ledPin 13

int led = 13;
int button = 12;

int ledState = LOW;
int buttonCurrent;
int buttonPrevious = HIGH;

byte pinState = 0;
String SetUp = "setpar serout setmapping2 YUYV 640 480 30.0 JeVois SaveVideo";
String StreamOn = "setpar serout streamon";
String Start = "setpar serout start";
String Stop = "setpar serout stop";
String StreamOff = "setpar serout streamoff";

void setup()
{
  Serial.begin(115200);
  pinMode(button, INPUT);
  pinMode(led, OUTPUT);

  // define pin modes for tx, rx, led pins:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  pinMode(ledPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  
  Serial.println(SetUp);
}

void loop()
{
  buttonCurrent = digitalRead(button);

  if (buttonCurrent == HIGH && buttonPrevious == LOW)
  {
    if (ledState == LOW)
    {
      ledState = HIGH;
      Serial.println(StreamOn);
      Serial.println(Start);
    }
    else
    {
      ledState = LOW;
      Serial.println(Stop);
      Serial.println(StreamOff);
    }
  }

  digitalWrite(led, ledState);

  buttonPrevious = buttonCurrent;
}

You need to remove the "setpar serout" that is in most of your strings. Basically, you should println() this to JeVois:

setmapping2 YUYV 640 480 30.0 JeVois SaveVideo

to setup, then 

streamon

to start video streaming, etc
