The Logic Trainer — learn digital logic by building real circuits, not watching simulations.

A standalone, battery-powered board that lets you wire up logic gates with jumpers and see results immediately on LEDs and a 7-segment display. No soldering, no power supply, no software — plug in 3×AAA batteries and start building.

Trusted by the electronics community. Our earlier project Logic Gates was featured on EEVblog and reviewed by Jazzy Jane. The Logic Trainer is the next iteration, redesigned around feedback from learners, universities, and the global hobbyist community.

What makes it different:

• World's first learning board with a built-in variable clock for sequential logic experiments (0.2 Hz to 5 Hz, or step manually) — flip-flops, counters, and shift registers become tangible, not just diagrams.
• Jumper-tolerant design — incorrect connections won't damage anything. Experiment freely.
• Companion curriculum included — structured exercises designed specifically for this board, freely available at logicgat.es/logic-wiki.

A concrete example: in under 15 minutes and a handful of jumpers, a learner can wire the BCD counter to the 7-segment display, drive it with the onboard clock, and watch a working digital counter come to life — then slow the clock to step through each state and see how sequential logic actually behaves.

Who it's for:

• Parents learning alongside their kids — no electronics background required; the wiki walks you through every step.
• Students working through a digital logic course who want hardware to match their textbook.
• Educators looking for a classroom-ready, durable, low-setup teaching tool.

Specifications:

Combinational logic:

• Two each of: buffer, NOT, AND, OR, XOR, NAND, NOR, XNOR gates
• Multiplexer

Sequential logic:

• Variable clock: 0.2 Hz to 5 Hz, or manual step
• 4-bit memory
• 8-bit shift register
• Binary-Coded Decimal counter

Input / output:

• Manual switches
• Output indicator LEDs
• 7-segment display

Power: 3×AAA batteries (not included).

What's in the box: The board itself, ready to use out of the box. A protective case and a set of female-female jumper cables are available as add-ons. Order the case with the board and we'll pre-install it for you — it ships assembled and ready to use.
