Smart Power Switch

Introduction

The purpose of this project is to create a smart power switch that can turn on or off an appliance based on the ambient light level. The project will use a Raspberry Pi Pico, a photoresistor, a relay module, and an LED to sense and control the power switch. The project will also use a web app to display the light level and the switch status on a web page.

Using shared data space

While working with git on major projects, one problem developers usually feel is the huge amount of data that is hosted in each working directory. For example, my busybox folder currently hosts 18MB of source code and 20MB in .git. While code can be compressed to 2.5MB, the git data is already compressed and remains 20MB.

As soon as you work on several branches at the same time, because you are following different use cases of the same software package, it's useful to have different folders, with different checkouts of the same project, to avoid switching branches too often, as each time you need to recompile everything, which takes time. In this situation, the amount of common history becomes an heavy load, both on the work disk and on the backup device. Clearly, most git objects are repeated in the various folders, as past history of the package is the same, and local differences across branches are relatively little.

To avoid such data duplication, git allows to specify ot
