Logic Lab allows exploration of digital logic gates #Education
Technoblogy has a new version of their Logic Lab out which provides a selection of 12 logic gates that can interconnect with patch cables to make a variety of different logic circuits.
You can enter inputs using switches and display the outputs on five coloured LEDs. It’s ideal for experimenting with and learning about logic.
This new version of the Logic Lab is identical in operation to the original, but is implemented using discrete “1G” CMOS logic gates; the original implemented the logic using an AVR microprocessor. It is intended for people who were discouraged from building the original circuit because of the need to program an AVR microcontroller, and it also involves easier surface-mount soldering.
The original Logic Lab article included nine logic problems. Since then I’ve devised five more problems, a logic game, and a logic puzzle.
The board is powered by two AA batteries.
You can read more here and get the Eagle files or Gerber files for the PCB on GitHub.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
