Circuit Description of Arduino weighing Machine. Arduino Scale With 5kg Load Cell and HX711 Amplifier: This Instructable describes how to make a small weighing scale using readily available off the shelf parts.Materials needed:1. Push-to-on Switch x 1. When I want to setup my arduino the message "The Arduino source 'HX711/HX711.h' for libraries 'ExampleAddon/HX711' cannot be found. The HX711 and Load cell are used in building a weighing … The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine. Then this amplified value is fed to the Arduino where the output of HX711 is converted into the weight values in grams. Clock. Learn How to Interfacing HX711 Load Cell Amplifier Module with Arduino. Come explore Arduino projects! Add the possibility to define a custom “zero” condition. Required fields are marked *. Yes my libraries are up to date , still same error : no matching function for call HX711::HX711(int,int); . The HX711 module amplifies the low-voltage output of the load cell and sends it to the Arduino so that the Arduino eventually calculate weight from this data. 10K variable Resistor x 1. Be aware that applying force to the cell load should not be instantaneous. * Load Cell HX711 Module Interface with Arduino to measure weight in Kgs Arduino pin 2 -> HX711 CLK 3 -> DOUT 5V -> VCC GND -> GND Most any pin on the Arduino Uno will be compatible with DOUT/CLK. Our philosophy is simple. In this Arduino Tutorial we are interfacing 40Kg load cell to the Arduino using the HX711 Load cell amplifier module.HX711 is a precision 24-bit analog to digital converter (ADC) designed for weighing scales and industrial control applications to interface directly with a bridge sensor. How to use the load cell module with Arduino, How to Interface PS2 Wireless Controller w/ Arduino, How to Install Android on Raspberry Pi [Full Guide w/ Images]. The main component of this project is a Load cell and HX711 load cell amplifier module.As you can see, one side is marked with ten kilograms. Arduino - this design uses a standard Arduino Uno, other Arduino versions or clones should work also2. The HX711 is a 24-bit analog-to-digital converter which fits perfectly to weight scale applications. They come with a wide variety of weight ranges, starting from one kilogram up to a couple of hundred kilograms. Red (VCC) Black (GND) Data. This module is a high-precision analog-to-digital converter. The body is usually made of aluminum, alloy steel, or stainless steel which makes it very sturdy but also minimally elastic. Overview. 16×2 Alphanumeric LCD x 1. Arduino Weighing Machine Working. Then this amplified value is fed to the Arduino. ... been working on a project for school using a HX711 load cell and the code is not being able to be found in my library. Usually, there is an arrow on the module that shows the force direction. This Hookup Guide will show you how to get started with this amplifier using some of the various load cells we carry at SparkFun. This module does not use I2C communication. Then apply a force to it with your hand. Focus on one thing and be the best at it. It would be amazing if you put some source codes for AVR. The easiest way to get a weigh reading from these to an Arduino is to use the HX711 amplifier module. HX711 is a 24bit ADC, which amplifies and digitally converts the Load cell output.
