A timer is a simple counter! The input clock of microcontroller and operation of the timer is independent of the program execution.All the Atmel microcontrollers have Timers as an inbuilt peripheral.

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

[Kyle] has been hard at working building an 8-bit computer from the ground up. He’s using a set of logic IC’s for the various components, and some NVRAM chips to store the control words. What you see ...

Arithmetic Logic Units are combinations of digital logic gates that performs arithmetic and logical operations on binary numbers. For this project, an 8-bit ALU was made entirely of NAND gates only. A ...

Not content with your new, 1.4-billion-transistor Ivy Bridge processor? Maybe it runs too hot, or lacks the polygon-pushing powers that you require? Well, I've got just the thing for you: How about ...
