Just describe your idea. Codey writes the code, draws the wiring diagram, compiles it in the cloud, and uploads it straight to your board — all from one browser tab. No IDE, no driver hell, no setup.
The novel opens with a classic, high-stakes hook: the protagonist, , wakes up in an abandoned factory next to the dead body of a man he does not recognize. Beside him lies a blood-covered stone, suggesting a violent struggle.
Santiago utilizes the rugged landscape of the to mirror the internal chaos of his characters.
(The Liar) by Mikel Santiago is a masterclass in psychological suspense that has solidified Santiago's reputation as a leading figure in contemporary international thrillers. Released in 2020, it serves as the gripping first installment of the Illumbe Trilogy , set in a hauntingly atmospheric fictional town in the Basque Country.
: The fictional coastal town of Illumbe , characterized by winding cliffside roads and storm-battered houses.
: Reviewers often note the highly visual nature of Santiago’s prose, describing it as "cinematic" and reminiscent of a fast-paced film.
The primary conflict arises from Álex’s fractured memory. He has no recollection of the preceding 48 hours. Fearing he might be a murderer—yet instinctively doubting it—he flees the scene and begins a desperate, solitary quest to reconstruct the missing pieces of his life.
For readers searching for the El Mentiroso Mikel Santiago epub , understanding the depth of this "impossible to put down" narrative is essential to appreciating why it has captivated over a million readers worldwide.

: The setting is described as a place where "apparently, nobody has any secrets," though the plot quickly reveals a web of hidden pasts and communal lies.
Every Codey project comes with a real wiring diagram. Color-coded wires, labeled pins, and a complete connection table — exportable as PDF or printed straight from your browser.
Red for 5V, black for GND, signals in distinct colors — exactly how you'd draw it on paper, only neater.
Below every diagram you get a Wire From → To list with pin labels, so you can wire your circuit without guessing.
One click to download a printable PDF of the diagram — handy for workshops, classrooms or your own build log.
Codey ships with a library of common modules: OLED displays, DHT11/22, HC-SR04, servos, relays, MOSFETs, RGB LEDs and many more.
Codey works out of the box with the most popular development boards. Plug one in over USB, pick it from the dropdown, and start vibing.
The classic. ATmega328P @ 16 MHz, 14 digital I/O, 6 analog inputs. Perfect for beginners.
Compact ATmega328P board. Same brains as the UNO, breadboard-friendly form factor.
54 digital I/O and 16 analog inputs. The go-to when one UNO simply isn't enough.
The popular WROOM-32 module. Dual-core 240 MHz, Wi-Fi + Bluetooth, 30 GPIO.
Beefy S3: 16 MB Flash, 8 MB PSRAM, native USB-CDC. Two USB ports — Codey knows which is which.
RISC-V single-core, ultra-low-power, USB-C and a built-in OLED. Tiny but very capable.
More boards added regularly. Direct USB upload over Web Serial — no drivers, no Arduino IDE required.
If you love vibe coding with Cursor or Claude Code, you'll feel right at home in Codey. Same describe-it-and-it-builds flow — except Codey runs your code on a real Arduino or ESP32, not on a server.

Cursor and Claude Code are excellent general-purpose AI coding tools — we use them ourselves. They're just not made for blinking an LED on a microcontroller. Codey Online fills that gap.

Codey Online is built by OTRONIC, a Netherlands-based electronics company. We're passionate about making hardware programming accessible to everyone — from primary-school kids to professional firmware engineers.
We saw too many beginners give up on the traditional Arduino IDE because of driver issues, missing libraries and cryptic C++ errors. Codey closes that gap with modern AI and Web Serial — so you can stay in the flow and just vibe your way to a finished project.
