SparkFun LogicBlocks Kit

Digital logic is the foundation of every task that a computer can perform. So it's no surprise that to fully understand how computers and other digital electronics work, you need to be familiar with logic gates. The problem is that logic gates are not the "most tangible" topics until now.

LogicBlocks allow you to play with logic gates by literally plugging them together and observing the flow from an input to an output! Each LogicBlock represents a different logic function: The NOT block is a simple inverter, where the output is the opposite of the input. The AND block outputs a 1 only when both inputs are 1. The OR block outputs a 1 when either of the inputs is 1. There are also input blocks and splitter blocks.

Each block has a light onboard that illuminates to indicate the "true" state with a slight delay compared to the input signal. This way, you can toggle the switch on an input block and track the propagation of that signal through your logic tree. This delay also allows you to use the feedback cable to create new inputs based on the output of your logic circuit!

These things are really fun, even if you know nothing about electronics, and playing with them is the ultimate hands-on course in logic gates. This kit also includes our LogicBlocks Experimenter's Guide, which explains the basics of digital logic and the function of each block.
