Perhaps you should try some spelling variations:
"coder using arduino application programming" » "coder using arduino application program" (Expand search), "coder using arduino applications programming" (Expand search), "coder using arduino aplicado programming" (Expand search), "coders using arduino application programming" (Expand search), "cover using arduino application programming" (Expand search), "code using arduino application programming" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python 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 using arduino application programming\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder using arduino application programming ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder using arduino application programming") OR ("api python python python programming"))*.
