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.
Before MP4 became the universal standard, .3gp (3GPP Multimedia PTM) was the king of mobile video. It was designed specifically for 3G mobile phones to save space. The videos were tiny, often highly pixelated, and had poor audio quality. However, because they were small (usually under 5MB), they were perfect for the limited storage of Nokia and Sony Ericsson phones.
In the context of Indonesian internet history, "Meli" is often a name associated with early viral "amateur" videos. During this era, many videos were circulated with simple, clickbaity titles like "Meli 3gp" or "Video Meli Terbaru." AI responses may include mistakes. Learn more

The phrase is a nostalgic trip back to a specific era of the Indonesian internet—a time before high-speed fiber optics, 4K streaming, and TikTok. It evokes memories of the mid-2000s and early 2010s, when mobile technology was in its infancy and "viral" content was shared via Bluetooth rather than algorithms.
In this article, we’ll explore the cultural context of the .3gp era, the mystery of the "Meli" moniker, and why these keywords still linger in search engines today. 1. The Era of the .3gp Format
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. Meli 3gp Dulu
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. Before MP4 became the universal standard,
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. However, because they were small (usually under 5MB),
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. Cursor® is a trademark of Anysphere Inc.; Claude™ and Claude Code™ are trademarks of Anthropic PBC. Not affiliated with either company.
Start vibing for free. Upgrade for unlimited AI and pro power.
For students and hobbyists.
For makers and creators.
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.
