Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

Hackers [Navic] and [K.o.D] have fitted an Arduino Pro Mini and an array of components into an off the shelf rocketry kit to create a guided model rocket, taking the whole idea of Arduino-based spa… ...

The rest of the connections are pretty well described by the power circuit diagram (repeated left) and the annotated board photo (just above). The x, y and z-limit and probe inputs are all via ...
