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