Perhaps you should try some spelling variations:
"and computational python arduino programmable" » "and computacional python arduino programmable" (Expand search), "and computacional vpython arduino programmable" (Expand search), "and computacionais python arduino programmable" (Expand search), "_ computational python arduino programmable" (Expand search)
"using lines python python programming" » "using lines pythons python programming" (Expand search), "using lines piton python programming" (Expand search), "using lines pitons python programming" (Expand search), "using in python python programming" (Expand search), "using line python python programming" (Expand search), "using splines python python programming" (Expand search), "using linear 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: "((\"and computational python arduino programmable\") OR (\"using lines python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational python arduino programmable ) OR ( using lines python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational python arduino programmable") OR ("using lines python python programming"))*.
