Make Arduino-controlled Larson Scanners

Although it sounds like one, a Larson Scanner isn't a piece of test equipment, instead it's the name given to a horizontal strip of lights that flash in turn in both directions, similar to that of the car from the 80s TV show "Knight Rider". Making your own version for fun or experimenting is easily done with an Arduino and explained in the latest tutorial over at the tronixstuff website. John has explained how to make a small version using a solderless breadboard, and then a larger version using an Arduino-compatible circuit that can easily be programmed via a USBasp AVR programmer. For a quick demonstration check out the following video:

Furthermore there's some notes on selecting resistors for LEDs, working with switching transistors and also Arduino port manipulation. So visit the project page to learn more. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you find yourself flashing Arduino bootloaders onto various boards, working with AVR-based projects or uploading firmware to various projects - then you'll need our new USBasp - the USB in-circuit programmer for Atmel AVR controllers. Based on the original design by Thomas Fischel, it's fully compatible with the Arduino IDE and all three major operating systems, using the USBasp is a cinch.

You can select 3.3V or 5V target voltages, supply power to your project via theUSBasp and even update the firmware on board yourself.  Furthermore we've included the ICSP cable and microUSB cable to it's ready to use out of the box. 

 For more information including our Getting Started guide, design information and to order - please visit the USBasp product page. And to keep up with product announcements, we're on twitter and Google+ - so follow us for news and product updates as well.
