Perhaps you should try some spelling variations:
"coder localization using arduino programmable" » "node localization using arduino programmable" (Expand search), "nodes localization using arduino programmable" (Expand search), "core localization using arduino programmable" (Expand search), "coder localization in arduino programmable" (Expand search), "coder localization and arduino programmable" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder localization using arduino programmable\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( coder localization using arduino programmable ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder localization using arduino programmable") OR ("using codigo python python programming"))*.
