Dan's Programming Portfolio

My name is Dan Kretschmer and I like to make stuff and program stuff. I made this site to show some of my portfolio, proficiencies, and skills in the fields of Android app development, web development, robotics, and computer science. I also have a YouTube channel where I talk about tech topics like AI and programming.

About Dan

Most of my portfolio is comprised of Android apps: some action games but mostly hidden object games based on paintings from throughout art history.
I've made homebrew Arduino robots (with ATMega chips and off the shelf parts) and programmed them with C on the Android platform. I love robotics!
Languages: I can code a little of C (for Arduino projects), HTML, CSS, Java (for Android apps), and I'm learning Python.
Tools: I use Eclipse for Java, Android Studio for Android apps, IDLE, and Visual Studio Code. I've also been using Git Bash to commit my repositories to Github.
Moving forward: I love AI, ChatGPT, and Stable Diffusion for AI imagery. (ChatGPT helped me make this site!) I want to get into robotics, machine learning, and continue making games, apps, and websites.

Projects that I made

Python games and programs

Coded with Python in Vusual Studio Code.

Hidden Objects Game

Inspired by the hidden items in Henri Rousseau's paintings, Henri's Hidden Objects was written in Python using the Pygame library. You can play it on Itch.io or download the Python code from GitHub.

Atari Adventure Clone

Inspired by the Atari game Adventure, this game was written in Python using the Pygame library. You can download the Python code from GitHub. I also made a level editor for the game.

Web Scraper GUI

I wrote this web scraper that scrapes the day's headlines and saves them to an excel spreadsheet. It also notes the most frequent words for the day. You can download the Python code from GitHub.

Android apps

Coded with Java in Eclipse and published on app stores. Monitized with banner ads with Admob.

Arduino programs for microcontrollers and elecronics

I've made many microcontroller projects with either Arduino or my own ATMega328 off-the-shelf microcontrollers. One of the first projects I made was a Rudolph box where I put a red LED on a deer's nose, which when pressed played a short clip of Rudloph the Rednosed reindeer in beeps.

The image above is my homebrew microcontroller dubbed Dandroid. There were several Dandroids: a remote control car, a PONG clone with paddles, and this gas tester you see above as just a few examples. I loved to make the microcontrollers with each component and program them myself with C code written in the Arduino platform by using another Dandroid as a bootloader.

Arduino code example:

#include 
AStar32U4Buzzer buzzer;
int ledPin = 10;
int buttonCheckerPin = 11;
int val = 0;
boolean play = false;

void setup()
{
pinMode(ledPin,OUTPUT);
pinMode(buttonCheckerPin,INPUT);

}

void loop() {

val = digitalRead(buttonCheckerPin);
if (val == 0) {
  play = true;
}
 if (play == true){
delay(1000);
digitalWrite(ledPin,HIGH);
