+===== Remote control of a light bulb =====
+Author: Samuel Tănase
+=== Introduction ===
+The purpose of this project is to control a classic 230v light bulb remotely.
+It is intended to to force the light bulb to emit more light than the nominal value if the user wants this (with the risk to damage the light bulb).

+=== Hardware Description ===
+The components used for the project were the following:
+  * ESP32 board
+  * Custom PWM driver
+  * A light bulb
+  * 5VDC power supply
+  * Wires and connectors
+The electronic schema:

+=== Software Description ===
+This software part of this project consists of 3 software components:
+  * ESP32 software: connects to the internet using wifi, downloads a PWM value from the server periodically and sends the PWM signal to the PWM driver
+  * Android app: user interface for controlling the light bulb intensity, written using Qt C++
+  * Web server: used as a glue between the ESP32 board and the remote control app, written in PHP
