If you dig into Adafruit’s GFX library a bit — the drawing library that provides the backbone for most of our displays! — you’ll noticed a reference to Bresenham in the various line or circle functions. Jack Bresenham came up with a simple, efficient way to draw a straight line between two given points, and you come across it a lot on small resource limited embedded systems. Wikipedia has a good article on it, but if you’re interested in line drawing algorithms in general, this power point presentation does a good job of explaining how it really works. Once you understand Bresenham lines, you might want to dig a bit deeper and look at ‘Wu Lines‘ which add high-speed anti-aliasing to the line drawing equation.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
