Hardware/Enhancement: Making the code computationally effective on low-end hardwares(ESP32, Raspberry Pi 0, etc.)

[sachinbhat2001]

If you open a issue, here is the policy to follow:

1. It must be a bug, a feature request, or a significant problem with the
   documentation.
2. The form below must be filled out.

Here's why I have that policy: The issue might be hardware specific to work on and every contributor is welcome to use any hardware of choice and build on this particular algorithm. Therefore, as a maintainer, I would like to keep everything in track without any discrepancies.
