Titel:  [3.7] nodo + 5mm rgb led [OPGELOST 22-8-2014]
Hallo,

Ik wil graag een standmelding, via mijn Nodo, maken. Ik wil hiervoor een 5mm rgb LED aansluiten op de mini.
Moet ik nu een led nemen met een gemeenschappelijke kathode of een gemeenschappelijke anode?
En kan ik dan D9, D10, D11 gewoon aansluiten op de polen van de LED of moet er nog iets van bescherming tussen?

Hoor graag van jullie :D

Greetings

Niemand???

In het schema kun je zien dat de RGB Led die daar gebruikt wordt met de kathodes via een weerstand van 1k aan aarde ligt.

Oef,

Soms kan het zo makkelijk zijn :oops: :oops: :oops:
Ik ga er gemakshalve dan maar vanuit dat dit ook voor de mini geldt, alleen dan met andere pennen

Bedankt hoor

begin nu toch weer te twijfelen...

Als ik de plugin er bij pak:

2.Een poort mag niet meer worden belast dan 40mA. Sluit daarom nooit een led direct aan op een poort, maar gebruik altijd een voorschakelweerstand van minimal 470 Ohm.

is toch een beetje in tegenspraak met het schema.... :shock:

1k is meer dan 470... dus wat is het probleem?

Het probleem is, dat ik graag mee wil spelen, maar elektronisch niet goed onderlegd ben.... :D :D :D

Dus....dan vragen we.

Thanks

Ik denk dat je het te letterlijk neemt.
Poort - led - aarde moet inderdaad niet
Poort - led - weerstand - aarde of poort - weerstand - led - aarde is ok. De volgorde doet er niet toe.

Aansluiten zoals op het schema.

Ik weet niet precies wat je wilt met de standmelding, maar als je maar een kleur tegelijkertijd wilt hebben, volstaat bovengenoemd schema. Als je wilt gaan kleurmengen dan kun je beter de kathode aan de massa leggen en in elk van de drie anodes een weerstand van 1 k opnemen.
