I've recently stumbled upon the Hx711 module, and i found it to be great use in my graduation project.
I've connected the loadcell to the Hx711. and from the hx711 to the arduino board according top this guide here:
"Arduino Your Home & Environment: Arduino Hx711 Digital Scale"
I've a problem that whatever weight i put on my scale it give me a reading.
Here is the code:
#include <Hx711.h>
Hx711 scale(A2, A3);
// Connected A2 to DT
// and A3 to Clk
void setup() {
Serial.begin(9600);
}
void loop() {
Serial.print(scale.getGram(), 1);
Serial.println(" g");
delay(200);
}
I don't understand your problem, based on your description 
Sorry i just realised i wrote wrong, i mean whatever weight i put on top of the scale it doesnt give me any reading.
It keeps showing random number varying from high postive to negative numbers.
Can you provide a circuit diagram? You seem to receive much noise, how long are the cables between the components?
It looks like you might have just poked male jumpers through the HX711 holes into the solderless breadboard. You wouldn't be the first to make that mistake.
Connections to the HX711 need to be soldered.
PS: it's nice to embed photos inline, so people don't have to click the links...
@DaveEvans: Indeed i didnt soldered, but i thought even if i didnt solder atleast i would get some data, not accurate ofcourse but some readings
@DrDiettrich: From the loadcell to the hx711
Excitation+ (E+) or VCC is red
Excitation- (E-) or ground is black.
Amplifier+ (A+) is white
A- is green
As from the Hx711 to the arduino
GND to GND
VCC to 5V
DT to A2
SCK to A3
A2 and A3 i can change them in the code its just the sample i got from the library but i decided to use them as is
Thanks for the replies guys
@DaveEvans: i soldered but there is still no difference

These are some of the readings getting from the monitor
Ok, so now you've soldered the connections. That's good (provided you did a good job soldering).
But before you made your first post, did you read How to use this forum? (Apparently not, since your code was not in code tags.)
And, especially, item 4: "Try to solve your problem, or answer your question, yourself."
There is no evidence in your posts that you have done anything other than hook up the cell and HX711, and run the code.
What research and troubleshooting have you done to try to solve the problem or problems by yourself? And is there anything in the guide you were following that you haven't done?
There's tons of information on the web and this forum about using the HX711 with the Arduino (including the need for soldering the connections).
