Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...

Imagine a robot with an all-around bump sensor. The response to the bump sensor activating depends on the previous state of the robot. If it had been going forward, a bump will send it backwards and ...

One of the trends I saw at APEC 2013 this year was a move away from full –blown DSP/high level processor control to a “keep it simple” state-machine, less powerful, but lower power control solution ...

A recent EDN article dealt with a number of programming tips for embedded microcontrollers. One of those tips, using state machines, is a programming approach that is especially useful, yet probably ...

We’ll beat everyone to the punch: yes, actually building a working Turing machine, especially one that uses a Raspberry Pi, is probably something that would have pushed [Alan Turing]’s buttons, and ...

A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called ...
