@bonemap https://learn.sparkfun.com/tut... This is the sensor, I still don't know if firmata will work, but I just got it working with the serial in watcher. Just needed to seperate the values and make them Serial.Println like was suggested above. So the code was this. Then in izzy I just needed a second serial in watcher set to 2. 

#include <SparkFun_ADS1015_Arduino_Library.h>
#include <Wire.h>

ADS1015 fingerSensor;

void setup() {
  if (fingerSensor.begin() == false) {
     Serial.println("Device not found. Check wiring.");
     while (1);
  fingerSensor.setGain(ADS1015_CONFIG_PGA_TWOTHIRDS); // Gain of 2/3 to works well with flex glove board voltage swings (default is gain of 2)

void loop() {  
  int data_1;
  int data_2;
  data_1 = fingerSensor.getAnalogData(0);
  data_2 = fingerSensor.getAnalogData(1);
  Serial.print(1, DEC);
   Serial.print(2, DEC);
