Vom Widerstand Zum Arduino

1,565 views

Published on

IOT beginnt mit Elektronik. Wer mit IOT anfangen möchte, muss sich auch mit Elektronik auseinandersetzen. Für die meisten eine komplett neue Welt, aber Arduino & Co machen den Einstieg einfach. Dioden, Widerstände, Kondensatoren, Sensoren, etc. sollte man mal gehört haben. Man muss schon etwas Zeit investieren, aber die Hemmschwelle ist dank Arduino & Co stark gesunken.
