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...

App note from Maxim on using the MAX6954 to drive 14-segment monocolor LEDs, (PDF): This article is how-to guide, intended as a quick learning aid for engineers considering using the MAX6954 to drive 14-segment monocolor LEDs. The MAX6954 is a versatile display driver, capable of...

Peter Scargill writes, As it happens I’m experimenting on a 1284 chip which while being Arduino-compatible kind of, it does have another serial port, so without disconnecting my FTDI – I hooked up the second serial port to the home control serial and fired the DEBUG command at...

David Jones has another useful video tutorial about how to safely charge Lithium Ion and Lithium Polymer batteries with a bench power supply. The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you don’t have a special...
