+=== III. Hardware implementation ===
 The main components (besides wiring) used in this project are as follows:
   * 1 x **ESP32-WROOM-32D Espressif development board** - It uses an ESP32 microcontroller which is very cost effective while delivering many features for IoT applications. This project uses it to communicate with the app via Wi-Fi and directly with the actuators and sensors (via 14 digital pins).

-I used Arduino IDE, as Espressif ESP32-WROOM-32D board is compatible with it. The programming language is C/C++. Being an IoT project, it requires some overt the internet communication. That being said, I used the Arduino Cloud IoT platform from where I can control and monitor the feeder.

 All in all, the project turned out well, it is user friendly, robust and you cannot let your pet starving, at least without knowing.
-Future improvements may be:
+Future improvements may include:
   * Adding more LEDs for knowing when the device is on (without looking in the app) and when the RFID tag limit is reached.
   * Improve design for covering circuitry.
   * Get a better RFID reader with greater range.
   * Offer a way to configure Wi-Fi and email address without reuploading the code.
+  * Find another method for measuring how much food drops.
