Use a ps5 controller with an ESP32.

This is heavily based on the work of Jeffery Pernis to connect a PS3 controller to an ESP32, and the PS4-esp32 library.

PS3 controller: https://github.com/jvpernis/esp32-ps3

PS4 controller: https://github.com/aed3/PS4-esp32

Here's a video about how the ps4 library was made.

This repo can be downloaded as a zip file and imported into the Arduino IDE as a library.

The instructions on how to do this are base off what can be found here

1. You can add the ESP32 boards to your Arduino IDE by adding them to the Boards Manager:
   1. Open File -> Preferences
   2. Paste the following URL in the Additional Boards Manager URLs field: https://dl.espressif.com/dl/package_esp32_index.json
   3. Open the Boards Manager with Tools -> Board: "xxx" -> Boards Manager
   4. Look for esp32 (probably the last one in the list), and click install
   5. Select the ESP32 board you have with Tools -> Board: "xxx" under the section ESP32 Arduino
2. To install this library into your Arduino IDE:
   1. Click on the "Code" button in the top right of this page
   2. Select "Download Zip" (It's always a good idea to look through the code on this page first to make sure you know what you're downloading)
   3. In the Arduino IDE, navigate to Sketch -> Include Library -> Add .ZIP Library, then select the file you just downloaded

When a ps5 controller is 'paired' to a ps5 console, it just means that it has stored the console's Bluetooth MAC address, which is the only device the controller will connect to. Usually, this pairing happens when you connect the controller to the ps5 console using a USB cable, and press the PS button. This initiates writing the console's (or in this case an esp32's) MAC address to the controller.

To do this, you'll need to include the controller's ip address in the ps5.begin() function during within the setup() Arduino function like below where 1a:2b:3c:01:01:01 is the MAC address (note that MAC address must be unicast):

void setup()
{
    ps5.begin("1a:2b:3c:01:01:01");
    Serial.println("Ready.");
}

TLDR: Connect ps5 controller with phone through bluetooth. Get the controller's bluetooth MAC address (look in About settings of phone). Replace '1a:2b:3c:01:01:01' with your controller's bluetooh MAC. Same can be done with your ps5 console if more convenient.

Note: Only buttons and analog inputs have been tested. Other functions like rumble/lights/IMU might not work, but could possibly be implemented using the 'ps5ViewIncomingBits.ino' example.
