Bulb Controlled from Smartphone

[nakov]

Create an IoT project to control a bulb from a smartphone.

Detailed requirements:

• The bulb might be a low-voltage (e.g. a simple LED or battery-powered bulb) or high-voltage bulb (dangerous, don't do it without a mentor!).
• The controller might be of choice, e.g. Arduino, Raspberry Pi, ESP8266, Olinuxino, Micro:bit or other. Write your code in your favorite language. You may use a relay to control the power circuit or just use a LED lamp.
• The mobile app might be built on platform of choice: e.g. Ionic, React Native, Xamarin, AppInventor, Swift+iOS, Java+Android or other
• Your mobile app could communicate with the controller through a back-end server (e.g. a IoT cloud environment or MQTT broker) or use directly WiFi, Bluetooth or other connectivity.

Your project's source code should be in your GitHub profile, along with the full commit log, which demonstrates the development efforts over the time.

You might use cloud-based IoT backend platform like:

• https://blynk.io
• https://io.adafruit.com
• https://www.cloudmqtt.com
• https://thinger.io

We shall use the PlatformIO as IDE (development environment): https://platformio.org.
It is a plugin for Visual Studio Code for hardware projects.
