Perhaps you should try some spelling variations:
"coder codes _ microcontroller arduino" » "coder codes _ microcontrolador arduino" (Expand search), "color codes _ microcontroller arduino" (Expand search), "order codes _ microcontroller arduino" (Expand search), "code code _ microcontroller arduino" (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.

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