Overview You cannot imagine to use microcontroller without using any of its i/o pins. Finally its all about : taking input , processing it and generating output ! Thus i/o registers and their correct settings is indispensable part while learning to program any uC. We will learn how to use Atmel AVR’s GPIO ports and actually […]

The Classic ATtin85-20PU is a very simple project that is also very fun to make. It really is perfect for a parent/child combo because it’s quick! Builds in minutes. But it does teach several electronic hobbyist skills.There is a story behind my decision to become infatuated with signal lights. My friend invited me to his

Cree has announced the CV94D-FCC LED that integrates three emitters in a compact surface-mount device (SMD) package. The package includes tightly packed red, green, and blue (RGB) emitters enabling full-color signs or displays based on solid-state lighting (SSL) technology. Cree identified the target application as intelligent transportation systems, with a primary example being dynamically changeable signs that

I love LED chasers. A bunch of LEDs neatly turning on and off on a precise timing – lights running one way, then the other way… It’s relaxing, soothing, and hypnotic. There are so many LED chaser/scanner/sequencer circuits out there, some are made with discreet transistors, some based on logic ICs, and more and more

Cree XLamp® XP-P LEDs deliver high levels of intensity and optical control in a familiar 3.45mm2 XP footprint. These LEDs enable tighter beam angles and longer throw distances with up to 700lm available at maximum current from a very small LES. The XP-P LEDs are built to last in extreme applications with high operating temperature limits and

Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to

Some time ago I presented the Electronic Quiz I made when I was a kid. It can be used to solve quiz sheets. The big drawback is, that each number is hard-wired to one letter so there are 26 fix combinations. Those are fast to memorise, even more so if you are a kid. So I came up

One way to extend the functionality of the micro:bit is to use a board called moto:bit by SparkFun Electronics (approximately $15-20). It looks complicated and has many features, but it isn’t hard to run servo motors from it. Moto:bit allows you to run more powerful motors than the tiny micro-motor that you can run from the micro:bit

Who does not want to have stunning lamp which can display animations and sync with other lamps in the house? Right, nobody. That’s why I made a custom RGB lamp. The lamp consists of 256 individually addressable LED’s and all of the LED’s can be controlled via a smartphone app. Additionally, you can build multiple
