Accurate data using Arduino
The Raspberry Pi typically runs on event-driven Operating Systems. This mean that a queue of events gets processed by the processor as fast as the processor can handle it. Unfortunately, even if your processor is idle, there is still an overhead in the event system that causes significant problems with real-time sensors or applications.
There are real-time Operating Systems for the Raspberry Pi, but this will severely limit the capabilities that you have learned to use and love. Real-time Operating systems guarantee that an action, such as some code, will be completed in the predefined time. A very popular Operating System for these types of simple yet extremely accurate tasks is the Arduino family IC. They are amongst ...
