Perhaps you should try some spelling variations:
"coder propagation python arduino programmable" » "coder propagation method arduino programmable" (Expand search), "coder propagation path arduino programmable" (Expand search), "coder programmation python arduino programmable" (Expand search), "mode propagation python arduino programmable" (Expand search), "model propagation python arduino programmable" (Expand search), "modes propagation python arduino programmable" (Expand search)
"using solid python python programming" » "using solid pythons python programming" (Expand search), "using solid piton python programming" (Expand search), "using solid pitons python programming" (Expand search), "using logic python python programming" (Expand search), "using lib python python programming" (Expand search), "using solid method python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder propagation python arduino programmable") OR ("using solid python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder propagation python arduino programmable\") OR (\"using solid python python programming\"))*".
• Removing quotes may allow a broader search: (( coder propagation python arduino programmable ) OR ( using solid python python programming ))*.
