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 ...

The circuit was constructed to produce a frequency divider with the use of flip flops which are the basic building blocks of sequential logic circuits while forming a T flip-flop configuration. Toggle ...

Last time I talked about how to create an adder in Verilog with an eye to putting it into a Lattice iCEstick board. The adder is a combinatorial circuit and didn’t use a clock. This time, we’ll finish ...

Now that we’ve introduced a JK flip-flop, let’s look at some circuits that we can create using it as the core element, including the T and D flip-flops. In my previous column, we started to look at ...
