Denk Development Turns Four

The date of this blog post’s publication coincides with Denk Development’s fourth birthday (or rather founding day). Back in early 2016 I started to receive requests from people on the internet, who had seen my YouTube videos in which I […]

My Arduino Boilerplate Sketch

When starting a new Arduino project, one typically starts with a blank .ino file. Over the past years I have identified software patterns that appear across almost all of my Arduino projects. To better support those, I have created an […]

ShiftRegister74HC595 Arduino Library

The ShiftRegister74HC595 Arduino Library simplifies shift registers usage. It allows you to set single pins of your shift register either high or low, just like normal Arduino pins. It thereby removes the overhead of shifting out bytes that were created […]

ShiftRegister PWM Library

The ShiftRegister PWM Library enables usage of shift register pins as pulse-width modulated (PWM) pins. Instead of setting them to either high or low, the library lets the user set them to up to 256 PWM-levels. This post serves as […]

Port Manipulation and Arduino’s digitalWrite Performance

The widely used Arduino IDE offers many easy-to-use functions, one of them is  void digitalWrite(uint8_t pin, uint8_t val) . It sets one of the microcontroller’s pins to either high or low and serves well in many cases. However, it has a really poor performance, […]

Editor’s choice

If you just came here and do not know where to go, I recommend looking into these posts:

  • Digit Span Test (most viewed)
  • Cubic Spline Interpolation (math-heavy)
  • Commute Time Tracking (nice read)
  • Linear Relationships in the Transformer’s Positional Encoding (machine learning)
  • Corsairs3D (pirate game – arrr!)

Donate

I have decided to remove all ads from this page, because I just don't find it to be a nice way of making a few bucks a month.

Suggested values are $\sqrt{2}$, $\pi$, or the electron mass (without the $\times10^{-31}\text{kg}$), but you can also choose an arbitrary amount.
