I had been reading on using Arduino to make a load cell to test braking load of balsa bridges. now my problem is when I try to upload to my uno board I get this error. I have also included the code I'm trying to use. any help would be appreciated.
Arduino: 1.6.12 (Windows 10), Board: "Arduino/Genuino Uno"

this is the code

scale.begin(A1, A0);
Serial.println("Before setting up the scale:");
Serial.print("read: \t\t");
Serial.println(scale.read()); // print a raw reading from the ADC

Serial.println(scale.read_average(20)); // print the average of 20 readings from the ADC
Serial.print("get value: \t\t");

Serial.print("get units: \t\t");
Serial.println(scale.get_units(5), 1); // print the average of 5 readings from the ADC minus tare weight (not set) divided

scale.tare(); // reset the scale to 0

void loop() {

Serial.print(scale.get_units(), 1);
