For Arduino Uno click shield owners, three new projects from microcontroller-projects.com.
The entire Arduino/Genuino conundrum has been filling news headlines for the better part of 2015, but makers are probably more interested in project ideas than in politics and court-room drama. Luckily, the Arduino Uno click shield and click boards are as neutral as Switzerland. Whether your particular Arduino board has been produced in New York, Italy or Shenzhen, you can make use of these examples.
The first mini-project uses Arduino’s LED Control library to recreate Conway’s game of life with a pair of 8×8 clicks. It’s basically LED blinking with a marvellous mathematical twist. Starting from an initial pre-defined state and moving through successive time increments, each LED either lives or dies (turns on or off) depending on how many of the eight surrounding LEDs are on or off. The exact parameters dictate whether all LEDs will eventually turn off or whether they will evolve into a stable looping pattern.
Obviously the example doesn’t have any practical use, but it’s fun and insightful to see how complex patterns emerge from a simple set of rules. Cellular automata models are fascinating stuff (if nothing else, it beats conventional LED blinking any day).
Here’s how it looks:
For more practical-minded individuals, the Arduino rotating photo table might prove more interesting. It’s a hardware setup for creating 3D models of objects from photographs. A stepper click moves a disk on top, while a a relay click connected to the camera controls the shutter. And in this particular case, a thunder click serves as the model for generating the 3D render.
The microcontroller-projects blog is high quality with code examples provided, and great photography too. It’s a good idea to bookmark it.
