Udemy – Arduino + MIT App Inventor: Android-Controlled Hardware

Transform your smartphone into a powerful wireless controller and monitoring dashboard for real-world Arduino projects! Most embedded systems and robotics courses focus exclusively on writing C++ code inside the Arduino IDE, leaving the user interface as an afterthought. Conversely, many mobile app development courses never touch physical hardware. This course bridges that gap by combining Arduino microcontroller hardware with MIT App Inventor Android app development.

You will learn how to design custom Android apps without complex syntax, establish rock-solid Bluetooth Serial Port Profile (SPP) connections, and communicate bidirectionally with real physical sensors and actuators on your desk.

What You Will Build in This Course:

• Project 1: Wireless Bluetooth LED Controller — Learn circuit wiring on a breadboard, UART serial reading in Arduino C++, UI design in MIT App Inventor, and one-way command transmission (‘1’ and ‘0’) to control physical pins wirelessly.
• Project 2: Voice-Controlled Arduino Assistant — Integrate speech-to-text artificial intelligence using Android’s SpeechRecognizer component to command your Arduino hardware hands-free using natural voice phrases (“Turn On”, “Turn Off”).
• Project 3: Smart Fire Alarm & Sensor Telemetry System — Master reverse data flow: stream real-time digital flame sensor readings from Arduino over Bluetooth to your phone, implement automated Clock timer polling in App Inventor, and trigger mobile alarms and visual warnings.
