Wheatstone bridge formation of Load Cell:

HX711 (24 bit Analog to Digital Converter)

HX 711 is a precision 24-bit analog to digital converter (ADC) specially designed for Weigh scales and industrial control applications to interface directly with a bridge sensor.

Simply connect Load cell wires to the HX711 module based on their color, then connect DAT (Data) pin to Arduino Analog pin A1 and connect CLK (Clock) pin to Arduin0 Analog pin A0, Put Vcc and GND supply from Arduino power source pins.
