Single Digit Big Display module using 74HC595 IC project will display large size 7 segment single digit number. 3.5inch height, which can be visible over large distance.  More digit can be connected serially to each other easily connector. This circuit is a single digit seven...

by 4D Systems @ instructables.com: The main objective of this project is to show how to interface a uCAM-II serial camera to 4Duino. uCAM-II is a highly integrated micro serial camera which could be controlled by any host that requires a video camera or a JPEG compressed still camera...

By Graham Prophet @ edn-europe.com: Distributor Mouser Electronics has Texas Instruments’ OPT3002 light-to-digital sensor; the device promises improved system performance over standard photodiodes and photoresistors. The fully-integrated OPT3002 delivers the functionality of an...

 In this video educ8s.tv shows us how to build an Arduino Robot that can avoid obstacles: The robot that we are going to build today is moving around and it can detect obstacles and avoid them. It uses a supersonic distance sensor in order to measure the distance from its front side....

Maxim presents its Cell-String Optimizer as the first IC to perform MPPT (maximum power point tracking) at low level in a panel; it allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects. by Graham...

The LTC7851 is a quad output multiphase synchronous step-down DC/DC controller with accurate current sharing between phases and differential output voltage sensing. This controller works in conjunction with external power train devices such as DrMOS and power blocks as well as...
