Of interest to the mathematically-inclined, or those teaching maths - or if you're interested in algorithms comes the following neat project by Arduino enthusiast Nick Gammon. He has created a prime number generator that generates and displays ascending prime numbers on a typical numeric display of your choice and also sent to the serial monitor. The process has been slowed down in the sketch to allow the observer to see the generated numbers, as shown in the following video:
Projects like these are an example of the more theoretical uses of the Arduino in education, and in a classroom situation discussion of various algorithms suggested by students could easily be implemented to test for speed and coding efficiency.
