[RISOLTO]Alimentatore 5v per striscia led RGB

-

alimentatore switching - sodial(r) ac 110-240v dc 5v potenza di commutazione fornitura convertitore sa10-05 https://www.amazon.it/dp/b00jzeu6bk/ref=cm_sw_r_cp_apa_mxiwzbsvsc2w3

salve, ho acquistato questo alimentatore per alimentare 21 led di una striscia led rgb da 5v che pieno carico (colore bianco) consumano 0,06a x 21led = 1,26a.

ho fatto la prova alimentando arduino da usb e la striscia led corrente.  il progetto finale vede entrambi alimentati corrente tramite lo stesso alimentatore.

purtroppo led sembrano in preda sbalzi di corrente, non prendono colori ben definiti e luccicano in continuazione, ho provato anche ad alimentare soli 4 led ( che alimentati da arduino funzionano alla perfezione) ma il problema persiste.

sbaglio io qualcosa?
potrebbe essere un difetto dell' alimentatore?
come potrei alimentare il tutto economicamente?

grazie in anticipo delle risposte.

utilizzo arduino nano v3

ma alimenti arduino con quel alimentatore e poi da arduino la striscia ? 
perchè così non va.  devi separare alimentazioni dall'alimentatore, e poi alimenti arduino e la striscia

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
