We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

Effective water management involves supplying water according to the real requirement, and thus measuring water is very essential step in water management systems. There are many water flow ...

Measuring speed with Arduino isn‘t something new, but the interesting part of this project that speed information is displayed on Flash application. Application has been built using Flex 4 and is ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

This Idea for Design points the way for a new design approach in laser power measurement using piezo-resistance on MEMS membranes. Suitably designed, such sensors can handle a wide range of laser ...
