NPN sur carte ARDUINO

-

bonjour tout le monde francophone  xd
je viens d'acheter une carte mega 2560, et j'attends l'arrivé du moteur stepper avec la carte uln2003a, pour les premiers tests pratiques, mais je ne comprends pas l'adaptation que font avec des résistances allant de 1kohm à 2,2kohm, dans le datasheet je ne trouve pas l'information de limite de tension et courant supporté à la base du transistor !

l'arduino donne du 5v 40mah, donc avec une résistance de 1kohm ça fait 5mah à la base ?
quelqu'un peut me dire quelle est la ligne du tableau du datasheet donne l'info sur l'entrée base ?

merci d'avance

bonjour,

pourrais tu préciser quel transistor npn tu utilises ?

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com
