Hi Kurt,

The Pi runs Linux which provides the timing functions to applications.

These functions are identical regardless the underlying hardware.

This is important to know, because it then helps when searching for resources; you're not restricted to searching for Pi-specific information related to timing, instead you can search for information based on the language you wish to use in Linux.

Having said that, it could be too soon to specify the sequence and timing you need. To take a step back, choose a language you're comfortable with (e.g. Python, C, etc) and then examine how to control the GPIO, and examine the time features available in an API offered in that language.

Some languages and middleware even provide higher-layer capabilities that are timing related (e.g. automatically execute code at a certain rate).

If you're open to trying any language, check out MagPi online magazine, it has loads of Pi-related beginner tutorials that address GPIO but also example games and apps, and the principles could be extended after playing with the basics.
