To create your own Ethereum-based cryptocurrency wallet using JavaScript and the ethers.js library, I'll guide you through the steps. The wallet will allow users to generate private/public key pairs, send and receive Ether (ETH), and view their balance.

Steps to Add a Menu Button for Launching a Web App:

1. Go to BotFather:

   • Open Telegram and search for BotFather.
   • Select the bot you've created.

2. Navigate to Your Bot Settings:

   • Type or select the /mybots command.
   • Choose your bot from the list.

3. Configure the Menu Button:

If your Raspberry Pi monitor keeps going into sleep mode or blanking after inactivity, this is due to the default power management settings. You can disable these settings to prevent the screen from sleeping. Here's how:

1. Disable Screen Blanking via raspi-config

You can use the Raspberry Pi configuration tool to disable screen blanking:

1. Open the terminal.
2. Run the configuration tool:

         sudo raspi-config

Open Terminal and right

sudo nano /boot/cmdline.txt

Now remove console=tty1

console=serial0,115200 console=tty1 root=PARTUUID=f29da198-02 rootfstype=ext4 fsck.repair=yes rootwait
and save the cmdline using ctrl+O and close the terminal using ctrl+x

To automatically detect the UUID of the USB drive and mount it on insertion, you can modify your script and udev rules to use the UUID instead of relying on device names like /dev/sda1. Using the UUID ensures consistency, as UUIDs are unique and won't change, even if the device path (e.g., /dev/sda1, /dev/sdb1) changes.

To do this, you'll need to concatenate the corresponding alphabet sounds to form the word. You can use a library like pydub to handle the audio processing, allowing you to merge the sounds smoothly.

Here's an example of how you might approach this in Python:

1. Install the required libraries:

If you haven't already installed pydub, you can install it using pip:

pip install pydub

2. Load and concatenate the alphabet sounds:

Here's a simple example:

Test Event
{
  "thing_name": "myThingNew",
  "access_key": "AKIAXLU4V3LTW4PS6CCH",
  "secret_key": "W1fNG5hmmlEmX0KTSTuHX174dPc9itf7AZwyxbDR",
  "policy_name": "ESP32_Test_Policy",
  "certificate_arn": "arn:aws:iot:us-east-1:506060987111:cert/f1020e6ed117a7c2834f25fc3025f54d6ff5b7662d339c6d4367937a2a0d135d"
}

lambda_function.py 
import boto3

def lambda_handler(event, context):
    thing_name = event['thing_name']
    access_key = event['access_key']
    secret_key = event['secret_key']
    policy_name= event['policy_name']
    certificate_arn = event['cert

Open terminal and run this command for display configure

sudo nano /boot/config.txt
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

sudo nano /etc/lightdm/lightdm.conf

# for no sleep screen
[Seat:*]

xserver-command=X -s 0 dpms

 1. Editing the /boot/config.txt with the following changes:

At first open terminal and update the system using the following command:
