Use the bitWrite() function to set the value of the bit associated with each button input

To send a byte manually in UART communication, follow these steps:

  1. Set up the UART communication parameters, including baud rate, data bits, stop bits, and parity as needed.
  2. Prepare the byte you want to send in binary format (8 bits).
  3. Send the byte one bit at a time, starting with the least significant bit (LSB) and ending with the most significant bit (MSB).
  4. For each bit, wait for the appropriate amount of time based on the configured baud rate. Typically, you'll use a delay function or timer.
  5. Send each bit by setting the UART's TX (transmit) pin to the corresponding value (0 or 1) based on the bit's value.
  6. After sending all 8 bits, send any required stop bits and return the TX pin to its idle state (usually high).
  7. Repeat the process for each byte you want to send.

This process ensures that data is transmitted serially over the UART communication channel.

@rachna52 why the chatGPT copy/paste? what's the value added?

as a first post it's not so great...
