Tech Venture 101: The digital weigh-scale project(Part one)

-

So, I am still working on this project, though i just thought it would be nice to share my experience and hopefully get to finish it up ASAP.

For starters, Arduino is something you should really consider trying. Its so fun and you get to learn a lot and put your coding skills, research ability and technical skills to work. You need to experience it.


I wil start with a basic introduction of Arduino and the modules and technologies we will be using.

Well, Arduino has a variety of boards (from different manufacturers) you can choose from. Some of them include UNO(Most common), Mega, Red, LilyPad, Leonardo etc. I will be using Arduino Mega.

Arduino is open source and I guess thats why I love it the more. If you don't have it installed, visit Arduino to get it.

What we need for these project.

1. Arduino board and Software

The Arduino software basically uses a set of c/c++ functions as its programming language (The Arduino programming language.
 
An understanding of C++ is required as you will need to go through libraries and make corrections if need be and at times even make your own libraries.

2. A load cell, of course.

 A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. There are various types e.g.  hydraulic, pneumatic, and strain gauge. 

I will be using the strain gauge. 30kg max weight.
3. HX711 Load cell Amplifier

HX711 is a precision 24-bit analog to-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor.

4. A Bluetooth Module(Not necessary).

Well, to spice it up abit, I decided to add a bluetooth module. I am still not yet sure what I will do with it but hopefully, I will have figured it out before I get to it.

FYI i'm open to ideas. Please share with me what you think I could do.
5. The Code.
And lastly, I will finish up with sharing the code from my project. You are allowed to share yours too.

NB: you need lots of jumper wires and a breadboard.

Most of this items can be purchased online. If you need more information or you are unable to get to decide, just tell me on the comments below and I will help you.

MIT App Inventor

Instead of Android Studio, I decided to use MIT App Inventor 2 which is a web based, open source application that is maintained by MIT( Massachusetts Institute of Technology ) and is used for developing simple Android Aplications.  I liked and preferred it to Android studio because of its simplicity. Anyone can use it, even those who have very little coding experience can easily understand it and within no time be able to develop their own android applications. For those who are just beginning the programmer journey in Android, you can start with App Inventor for it to aid you in understanding basic concepts on Android App development then later start using Android Studio as it is actually the recommended and official IDE for Android Development. This is part of the code from the app (LoadBlue Control) I will be using for our Weighing Scale project. MIT App Inventor is a great way to start learning how to build applications for Android. Once you get a good hold of how to c

Tech ventures: The Bluetooth module(HC-05 zs-040)

The Bluetooth module was quite easy to understand. Though, there were some of the things that i noted and i would like to share with you so that you will even take a shorter time when you want to use it. HC-05 has 6 header pins(the STATE, RXD, TXD, GND, VCC, EN). It can work as both master and slave. This means that it can either initiate a connection or accept a connection from another device. Activating AT mode: Ensure that pin 34 is connected to 3.3v. With all the pins connected, disconnect the HC-05 from a power source. Start pressing the button below the EN header pin and switch on the module while doing it. Notice that the LED starts blinking slowly. You are now in AT mode which allows you to view and change the Bluetooth settings e.g the name of the module, the baud rate, whether or not it operates in master of slave mode. e.t.c.

The LoadCell Project

So I just finished my first draft code for the Load cell with Arduino and decided to share it. Feel free to make any modifications on it or create your own. Also, I decided to use the LCD module instead of the MCUFriend as i didn't want a lot of functionality in it. This is the code i used. It's pretty simple. /*  * Chemwen0  * By Doreen Chemweno  * Load Cell HX711 Module Interface with Arduino to measure weight in Kgs  Arduino   pin   5 -> HX711 CLK  6 -> DOUT  5V -> VCC  GND -> GND  Almost any pin on the Arduino Uno will be compatible with DOUT/CLK.  The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine. */ #include "HX711.h"  //You must have this library in your arduino library folder #include <LiquidCrystal_I2C.h> #define DOUT  6 #define CLK  5 LiquidCrystal_I2C lcd(0x3F,18,2); //important for display to work.
