Photography is my way of getting in touch with the surrounding environment. Keep your eyes open and you will see things you never payed attention to.
The Arduino-plattform is great for getting startet in the world of microcontrollers. I really enjoy working with ESP and Attiny controllers. Overall system management and a reliable communication is key.
I am fascinated by big amounts of data. There is so much you can read from data, visualize it and learn. With the right tools you can extract information you never thought of.
