Perhaps you should try some spelling variations:
"using computing using arduino programmable" » "using competing using arduino programmable" (Expand search), "mining computing using arduino programmable" (Expand search), "using conducting using arduino programmable" (Expand search), "using computing ufcg arduino programmable" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: "((\"using computing using arduino programmable\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( using computing using arduino programmable ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computing using arduino programmable") OR ("using in python python programming"))*.
