I started photo-etching circuit boards when I was 8, and at 11 was haunting the halls and computer science labs at the local college so much that I was invited by Professor Wayne Ayott to audit his software and hardware design courses.

Over my career I have used C#, ASP.NET, Node, C++, MFC, Assembler, Basic, and a long list of now dead technologies all the way back to Clipper on applications for the military, commercial ventures, medical research and the labour movement. Through my medical informatics work I came to know what real-time and mission-critical really mean… just try being part of the critical path when an expectant mother goes into labor.

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...

I was a Software Support Engineer for many years using various legacy enterprise systems before learning UNIX and Windows programming - the latter largely in my own time. In my last few years of employment I spent more time in actual development.

Since retiring I have been learning some of the newer technologies (C#, .NET, WPF, LINQ, SQL ...) that I never used in my professional life, and am actually able to understand some of it.

One day I hope to become a real programmer.

Challenge 1 - Build an Arduino LED binary counter

  • 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
  • Set up the Arduino IDE (online or Desktop)
  • Follow the instructions provided in the above 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 below to generate your secret code which you will enter in the Secret Code page.

Generating your Code

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 while logged in)  and find your member ID number directly 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.

Challenge 2 - Create Morse code using an Arduino

  • Get started by following the instructions in the tutorial article.
  • Check back here for instructions on how to generate a contest entry code.

Generating Your Entry Code

Start by opening your challenge 2 code in the Arduino IDE or in Tinkercad.

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

Once you have your member ID, look in your Challenge 2 code and find the line where your define your morse message. It'll look something like this:

const char *message = "codeproject\0";

Directly beneath this line, add the following line:

const char *memberNumber = "12345678";

Replace the digits 12345678 with your member ID.

Next, add the following code at the end of the setup() function:

String morseNumbers = "";
int length = strlen(memberNumber);
for(int i = 0; i < length; i++){
  const char *ch = strchr(characters, memberNumber[i]);
  int index = (int)(ch - characters);

We're almost done! Now we'll just need to use the Arduino serial monitor to get our contest entry code.

If you're using the Arduino IDE, connect your Arduino to your PC using a USB cable, and then click on the Tools menu and choose 'Serial Monitor'. You'll see a serial monitor window appear. Once you've done this, upload the code to your Arduino.

If you're using Tinkercad, click on the 'Serial Monitor' button at the bottom left of the code editor. You'll see a serial monitor display area open. After you do this, click 'Start Simulation' to run your new code.

When the new code runs, you'll see a Morse code message show up in the serial monitor window. It'll appear as a series of dots and dashes. Copy this message, and then navigate to the contest code entry page. Choose Round 2 in the drop-down box, and then paste the Morse code message from your Arduino serial monitor into the contest entry code box.

Then, click submit and if your code is correct, your contest entry will be recorded.

Challenge 3: Showcase 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.

Challenge 4: Demonstrate your 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.

How do I publish my articles?

Choose your topic 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)
