Summer Fun with Arduino Challenge

This competition has ended

The challenges

There are 3 challenges, starting from the fun and interactive to the deep and educational.

  1. Build an Arduino LED Binary Counter 

    Using your own Arduino starter kit (or the nifty web based Arduino simulator), we want you to build a simple LED binary counter by placing and wiring up a series of LED lights and connecting them to the Arduino. Here are the steps:
    • Please read Ryan's excellent Arduino starter articles to get you on your way. You can choose between using an Arduino device or using Tinkercad. Either way, your entry counts
    • Whip out your Arduino kit or use the Arduino Simulator provided
    • Set up the Arduino IDE (online or Desktop)
    • Follow the instructions provided in Ryan's articles to build a binary counter by placing and wiring up a series of LED lights and connecting them to the Arduino
    • Follow the instructions in the "How to Enter Challenge 1" tab to wire up a Secret Squirrel Code Generator. 
    • Run the app to find the ‘secret code’ that results from your work and then enter the result in the Code Entry page

    Simple right? Go dig out your Arduino and play!

    Estimated time to complete: 15 - 20 mins

  2. Showcase your other working Arduino projects

    Post a working Arduino project, with full source, as an article on CodeProject in the Arduino section as a CodeProject article.

    Your project can be for any purpose: a plant watering system, a solar energy tracker, a security system, or something that randomly injects pics of Guy Fieri into npm packages. Whatever the purpose, just package it up and post your work as an article on CodeProject.

    Winners will be judged on innovation, usefulness, ease of use of the code on a real Arduino, and general presentation of the project.

    Estimated time to complete: 30 - 60 mins to write about 500 words 

  3. Demonstrate Your overall IoT Expertise

    If you’re an IoT expert, this is the place to show it off! Post an article on CodeProject that highlights your choice in IoT development.  

    The focus of this challenge is to teach concepts to readers unfamiliar with the technology (or teach readers how to stretch themselves with advanced concepts). Brief examples that are to the point are better than full blown projects. Focus on the concepts you are trying to teach.

    Topics may include tutorials, code samples and walkthroughs, intros on how to program new and emerging technologies (eg. LoRaWAN, Low power operation, Bluetooth, Mesh). Maybe you want to write about embedded or Raspberry Pi development, or HomeKit or Google Home integration, or Docker with IoT, Azure or AWS. The possibilities are endless; let your imagination go wild.

    Winners will be judged on clarity of ideas, readability, technical prowess and general presentation of the article.

    Estimated time to complete: Depends on the length of the article 

How do I show I’ve completed the Arduino LED binary counter challenge?

As part of the binary counter challenge, you’ll be adding a bit of C++ that turns your e-mail address into a personalized binary code. You will then be able to enter this code on the contest page. For instructions, see the notes in Challenge 1 above.

How do I publish my IoT contest articles?

Choose your topic, come up with a brilliant idea, write and submit your article to the Internet of Things chapter. Contestants have until the contest deadline to write and submit as many articles as they wish (each article should focus on a single technology or platform).

Chris Maunder
Founder CodeProject
Canada Canada
Chris is the Co-founder, Administrator, Architect, Chief Editor and Shameless Hack who wrote and runs The Code Project. He's been programming since 1988 while pretending to be, in various guises, an astrophysicist, mathematician, physicist, hydrologist, geomorphologist, defence intelligence researcher and then, when all that got a bit rough on the nerves, a web developer. He is a Microsoft Visual C++ MVP both globally and for Canada locally.

His programming experience includes C/C++, C#, SQL, MFC, ASP, ASP.NET, and far, far too much FORTRAN. He has worked on PocketPCs, AIX mainframes, Sun workstations, and a CRAY YMP C90 behemoth but finds notebooks take up less desk space.

He dodges, he weaves, and he never gets enough sleep. He is kind to small animals.

Chris was born and bred in Australia but splits his time between Toronto and Melbourne, depending on the weather. For relaxation he is into road cycling, snowboarding, rock climbing, and storm chasing.

EE degree, first taste of programming was 6502 assembler. Toyed with BASIC a little, but my first real projects were in x86 assembler. From there I went to C, working on 80186/NEC V30 embedded systems and frontend PC apps for them. After that it was OCX development in C++, consuming those custom OCXes and DLLs in a Visual Basic front end. Currently working for a website application, where I wear multiple hats including System Administrator, Network Administrator, Database Administrator (MS SQL), SQL programmer, ASP programmer (VB.Net, some C#), JavaScript programmer. Currently moving our web application to the Azure Cloud. So I can hang up a few of those hats Smile | :) For fun I like to play with embedded systems, Arduino and recently a Raspberry Pi that I won in the Code Project Arduino challenge. That has got me interested in Python.

Israel Israel
Born in Hungary, got my first computer at age 12 (C64 with tape and joystick). Also got a book with it about 6502 assembly, that on its back has a motto, said 'Try yourself!'. I believe this is my beginning...

Started to learn - formally - in connection to mathematics an physics, by writing basic and assembly programs demoing theorems and experiments.

After moving to Israel learned two years in college and got a software engineering degree, I still have somewhere...

Since 1997 I do development for living. I used 286 assembly, COBOL, C/C++, Magic, Pascal, Visual Basic, C#, JavaScript, HTML, CSS, PHP, ASP, ASP.NET, C# and some more buzzes.

Since 2005 I have to find spare time after kids go bed, which means can't sleep to much, but much happier this way...

Free tools I've created for you...

Project Verification

Please read Ryan's excellent Arduino articles: Using an Arduino device or using Tinkercad.

Once you have your secret code please enter it in the Enter Code page.

Once you have your Arduino (or simulation) up and running it's time to add a little code to generate a code that you will enter in our contest system to prove you've completed the challenge. It’ll only take a few easy steps to make your Arduino generate the contest code.

First, open your CodeProject profile page (click on your name at the top right of CodeProject.com while logged in)  and find your member ID number directly under above your profile picture.

In the Arduino IDE or Tinkercad code window, paste the following function at the top of the file before any other code:

uint8_t Hash(String str)
{
   uint8_t hash = (uint8_t) str.length();
   for (uint8_t i = 0; i < (uint8_t) str.length(); ++i)
   {
      hash = (uint8_t) (((hash << 5) ^ (hash >> 3)) ^ str[i]);
   }

   return hash;
}    

Next, inside the BinaryCounter::increment() method, find the line that reads:

binaryDigits = getBinaryDigits(valuetoShow)

an change it to:

binaryDigits = getBinaryDigits(Hash(“00000000”))

Now, replace the string of zeros with your CodeProject member ID.

If you’re using Arduino hardware, connect the Arduino hardware to your PC and use the Arduino IDE to upload the code. If you’re using Tinkercad, you don’t need to do anymore more with your code as all the changes you make are available to the simulated Arduino immediately.

Proceed to the next section if you’re using a physical Arduino. If you’re using Tinkercad, skip ahead to the ‘Tinkercad Instructions’ section.

Hardware Instructions

  • If your Arduino is plugged in to a power source, unplug it.
  • Find the wire that connects analog port 0 on the Arduino to the breadboard
  • Unplug it from the breadboard, and plug it into the top negative power rail on the breadboard. Leave it plugged in to analog port 0 on the Arduino.

  • Connect your Arduino to a power source. The LEDs will light up and give you an 8 digit code to enter. If the LED is off, it represents a 0. If it is on, it represents a 1. For example, the LEDs in the image below represent the code 01110010.

Tinkercad Instructions

  • Delete the wire connecting analog pin 0 on the Arduino to the breadboard.
  • Connect a new wire from analog pin 0 on the Arduino to the upper negative power rail on the breadboard:

  • Click the ‘Start Simulation’ button. The LEDs will light up and give you an 8 digit code to enter. If the LED is off, it represents a 0. If it is on, it represents a 1. For example, the LEDs in the image below represent the code 01110010.
