This video shows the Arduino breadboard with wire link kit (product number A000032) being unpacked. A simple Arduino circuit is built on the breadboard. The review can be found at: http://startingelectronics.org/reviews/tools/arduino-breadboard-review-a000032/ In the video, a pre-loaded program on the Arduino Uno board flashes the breadboard LED on and off. ... https://www.youtube.com/watch?v=mQn8T6n8Nqo

Find the details at: http://startingelectronics.org/software/VHDL-CPLD-course/tut19-up-down-counter/ The counter counts up to 255 and the wraps around to 0. When counting down, the counter counts down to 0 and the wraps around to 255.

This LED "Open" sign is an open-source hardware and firmware project. Source files and project details can be found at: http://startingelectronics.org/projects/LED-open-sign This project is for an "Open" sign that could be used in a shop or restaurant. The microcontroller based control board can be used to control any LED sign of your design. An ATtiny2313 microcontroller from Atmel is used in the design. Circuit diagrams, source code and building information are available at the above link.
