Learn Assembly programming and binary operations by painting little pixel art pieces. The app teaches different operations in each of the ten chapters. For each of the chapters you program an image with a limited set of commands. Eight rows of 8-Bit Registers turn into your canvas. Use Assembly to manipulate the values in every register, thus creating an 8x8 painting. 'The Assembler' was made as a small and fun introduction to Assembly, Programming and the Binary system that powers it all. The first version of this app was made for the Swift Student Challenge 2022 and won! I hope that you enjoy this project as much as I have.

The best way to understand the working principle of computers is to get hands-on experience and build computer systems from scratch. This is a teaching and practice software for computer systems, which can also be viewed as a puzzle game. We have referred to two books, "Code: The Hidden Language of Computer Hardware and Software" and "The Elements of Computing Systems: Building a Modern Computer from First Principles", and designed various levels of challenges with different difficulties in a progressive manner. This makes it easier for everyone to start building simple yet powerful computers from the bottom-up hardware logic, and to better learn various aspects of computer knowledge.
