Piko: Learn Electronics

Learn how electricity, circuits, and sensors actually work. 39 lessons, no kit required, nothing to buy. Understand it first; build it when you are ready.

Piko teaches you electronics from zero — not by memorizing formulas, but by understanding what is actually happening.

Every lesson answers one question and stops. No walls of theory, no jargon dumps, no code to write.

THE BEGINNER PATH — FREE Thirty-nine lessons across five worlds:

• Energy — What is happening when something electrical works? Voltage, current, resistance, and safe paths. • Your first creation — Meet the parts, read a breadboard, orient an LED, check a circuit before power. • A board that controls — What an ESP32 is, and how one output becomes light, color, and sound. • A board that senses — Buttons, sensors, thresholds, and turning a reading into a decision. • Create with an agent — How to describe a result, give context, ask for a plan, and verify it.

NO MATERIALS NEEDED You can complete the entire Beginner path without buying anything. Circuits are explored on screen, including two interactive exercises where you wire the circuit yourself and watch it respond.

If you do own an ESP32 and a breadboard, the lessons map directly onto real parts — but nothing here requires them.

PRACTICE THAT MEANS SOMETHING Piko tracks Understood and Built separately. No inflated progress bars. The Practice tab returns you to the one idea worth reinforcing, not a filler list.

PIKO PLUS The Beginner path stays yours for free, forever. Piko Plus opens five specialized routes with thirty more lessons:

• Smart home — a room that senses and responds, and stays safe when links fail • Robots and movement — motion with purpose, and stopping safely • Art, lights, and sounds — physical input as coherent expression • Sensors and nature — honest measurement of the environment • Physical AI — perception that does not hide uncertainty

Plus also includes the new routes and challenges added over time.
