CCA Remote vs CarHA

Control your microcontroller directly from your smartphone – no hardwiring, no complicated software. With CCA Remote, you can build a custom dashboard with buttons, sliders, joysticks, and displays in minutes. Developed at HTL Anichstraße – for everyone who wants to get more out of their DIY projects. WHAT YOU CAN DO WITH IT - Easily build your own custom control interfaces via drag-and-drop - Connect to the controller via Bluetooth (BLE) or Wi-Fi - Automatically generate Arduino code – no manual programming required - Save, lock, and share profiles for different projects - View live readings as a bar, gauge, chart, or LED status - Remote profiles can be saved directly on the controller and are automatically transferred to the app upon connection - Multilingual user interface (German, English) - Element dependencies: Control elements can be enabled/disabled depending on other elements - System backup and restore of the entire app configuration CONTROL AND DISPLAY ELEMENTS - Control: Button, Slider, Switch, Joystick, Text Input, Color Picker, Selector Switch - Display: Display, Label, Bar, Gauge, Chart, Status LED, Icon - All elements fully scalable and customizable. SUPPORTED HARDWARE - ESP32 – Native BLE & Wi-Fi - ESP8266 – Wi-Fi - Arduino Uno / Nano – BLE via HM-10 module - Raspberry Pi Pico 2W and ESP32 – BLE & Wi-Fi (MicroPython) LIBRARY & GETTING STARTED The free CCARemote library is available on GitHub for Arduino and MicroPython. The integrated code generator automatically creates the complete sketch – including setup(), loop(), and all variable declarations. ORIGIN Originally developed as part of a diploma thesis by L. Eder and E. Duyar at HTL Anichstraße Innsbruck. This current version was further developed and published by A. Eckhart with the permission of the original authors.
