so i dont know if i have a hardware, firmware, or software problem, 
or perhaps the problem might even be that i dont know what im doing 
and its something really simple. i have a hk711 board and some load 
cells connected to an arduino, and the code used is example code from 
the adafruit hk711 library, so i at least know there shouldnt be any 
issues from the code. with that being said, this is my output. i can 
screen share (and would personally prefer it) if needed. for 
thoroughness sake ill also post the code

#include "Adafruit_HX711.h"

// Define the pins for the HX711 communication
const uint8_t DATA_PIN = 5;  // Can use any pins!
const uint8_t CLOCK_PIN = 4; // Can use any pins!

Adafruit_HX711 hx711(DATA_PIN, CLOCK_PIN);

void setup() {
  Serial.begin(115200);

  // wait for serial port to connect. Needed for native USB port only
  while (!Serial) {
    delay(10);
  }

  Serial.println("Adafruit HX711 Test!");

  // Initialize the HX711
  hx711.begin();

  // read and toss 3 values each
  Serial.println("Tareing....");
  for (uint8_t t=0; t<3; t++) {
    hx711.tareA(hx711.readChannelRaw(CHAN_A_GAIN_128));
    hx711.tareA(hx711.readChannelRaw(CHAN_A_GAIN_128));
    hx711.tareB(hx711.readChannelRaw(CHAN_B_GAIN_32));
    hx711.tareB(hx711.readChannelRaw(CHAN_B_GAIN_32));
  }
} 

void loop() {
  // Read from Channel A with Gain 128, can also try CHAN_A_GAIN_64 or CHAN_B_GAIN_32
  // since the read is blocking this will not be more than 10 or 80 SPS (L or H switch)
  int32_t weightA128 = hx711.readChannelBlocking(CHAN_A_GAIN_128);
  Serial.print("Channel A (Gain 128): ");
  Serial.println(weightA128);
