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 ...

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 ...

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 ...

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 articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
