The idea of using triangulation for distance measurements is well known since Pythagorean time, when his brilliant formula become available for mathematicians. What is new in this design, is lasers power control via “blooming” effect of CMOS camera. Here this “negative” effect was put to work instead of ADC. No need high price “no-blooming” camera!

The easiest way to connect an audio signal to your arduino, is to build a simple 3 components (2 resistors plus cap) circuitry shown on the first drawings on right side. Disadvantage: there is no amplifier, and consequently sensitivity would be low, hardly enough to work with headphones jack output. For low level signals, like

Communicating with a host computer can allow a simple Arduino-based system to gain access to a wide variety of devices and information. Most people link an Arduino to a host using serial communications across a USB connection with custom code running on the host to send information to the Arduino or receive it in return,

Introduction An introductory Arduino programming guide for artists and hobbyists Leads readers from basic through to advanced C programming concepts Fast-paced tutorials for developing working Sketches (the name given to Arduino programs) Fills the gap in the market left by the many books that concentrate mainly on the hardware side of using Arduino Filled with
Programming Arduino Getting Started with Sketches by Simon Monk E-Book Continue Reading
The other day I was confronted with an interesting problem, I needed to control a series of lights from an interaction on a computer screen and it had to be as inexpensive as possible. I instantly thought of an Arduino. It had everything that I needed, more than enough I/O, an integrated USB and its only
How to control LED’s with Processing and Arduino Continue Reading
Intro: RFID Cat Door Only the pet with the correct RFID tag can unlock this specific cat door/flap. Arduino is responsible for overseeing the process. It features a custom antenna large enough to function as a gate, enabling the animal to easily and consistently activate it. Some methods and techniques are borrowed from my previous
