Arduino Bluetooth Control App

@aman720gupta

Hi ?, I’m Aman Gupta, a Senior Engineer with 11+ years of Android development experience, including Arduino + Bluetooth (HC-05) hardware integration. I’ve delivered multiple IoT and control apps with custom UI, real-time device communication, and smooth user experiences. Why I’m a great fit: Strong expertise in Android app development with Kotlin/Java. Hands-on experience integrating Arduino Uno with HC-05 for reliable command control. Skilled in designing customizable UI/UX with icons, backgrounds, and status indicators. Experience building apps for real-time hardware control with minimal latency. My approach: ✅ Develop an intuitive on/off switch control via Bluetooth commands. ✅ Include custom monochrome icons and background selection options. ✅ Show clear on/off status indicators synced with Arduino feedback. ✅ Ensure stable HC-05 connectivity and error handling. ✅ Deliver signed APK + full source code with documentation. I’ve built similar projects like Amp Intel OTS (Bluetooth hardware control) and FitAnyWhere (IoT-connected devices), ensuring stable performance and a polished interface. Could you confirm if the app should support only one switch or allow future expansion for multiple devices?

Hi, I can develop a fully functional and visually appealing Android app to control a switch connected to your Arduino Uno via the HC-05 Bluetooth module. The app will feature reliable on/off control with real-time status indicators, along with a customizable interface that allows you to set simple monochrome switch icons and background images to match your preference. Using my experience in Android development, Arduino integration, and UI/UX design, I will ensure a stable Bluetooth connection, smooth performance, and an intuitive layout. Deliverables will include the Android APK, complete source code, the Arduino sketch for HC-05 communication, and clear documentation for pairing, operation, and customization.

@dwashil3000

I have done a similar one. I am interested to do this too. Pls do give me a chance to do it. I am sure you will hire me again after this project too. Hoping to hear from you soon. Thank you

@nyeke

Instead of using Android studio I will use the MIT app inventor which will provide a fast and flexible means of having the Android application needed for system. The Arduino Uno Microcontroller is the ideal choice for this project

@devanshbhana123

I am a 2nd year Software engineering student and I personally made the same android app project in my first year. I made a bluetooth door lock system with HC05 Module. Which used to unlock a door lock by a entering a PIN or using fingerprint in mobile phone. I can give you the C++ code for Arduino IDE and app's project code with APK file which can do the job. along with circuit mapping on your arduino UNO. I have completed a certification workshop for IoT engineering value added courses from my university. I also made a bluetooth controlled irrigation pump system, a mini obstacle detection rover with arduino UNO. I can build the app in 1- day or 2
