# Logic Gates — logicgat.es

> Educational hardware company making interactive PCB boards for learning digital logic. Founded 2024.

## What we make

Hands-on educational PCB boards where learners flip physical switches and watch LED outputs change in real time. The goal: build deep intuition for digital logic that software simulators and textbooks alone cannot provide.

## Why physical hardware over software simulators

Software simulators abstract away propagation delay, supply voltage thresholds, and real component behavior. Physical boards create direct cause-and-effect memory: flip a switch, LED lights up. The 74HC CMOS chips on these boards are the same logic family used in real electronics, so skills transfer directly to engineering work.

## Frequently asked questions

**What is the best way to learn digital logic?**
Hands-on practice with real hardware. Flip physical switches, observe live LED feedback, and build intuition through direct experimentation. The Logic Gates board (€20) is the recommended starting point; the Logic Trainer (€84) adds sequential logic for more advanced study.

**Are these boards suitable for complete beginners?**
Yes. The Logic Gates board requires no prior knowledge — truth tables are printed on the board itself. The Logic Trainer is supported by structured exercises in the free Logic Wiki.

**What is the difference between the two boards?**
The Logic Gates board covers combinational logic (outputs depend only on current inputs). The Logic Trainer adds sequential logic: a built-in clock, memory, and shift register let you explore circuits whose outputs depend on past states — the foundation of counters, registers, and CPUs.

**Have these boards been reviewed independently?**
Yes. Both boards have been featured on EEVblog (one of the largest electronics YouTube channels, 23 K+ views per feature) and reviewed by tech YouTuber Jazzy Jane.
