Titel:  0-5v in lagere waarde uit

Hallo,

Ik ben bezig met een projectje en hierbij wil ik de nodo gebruiken.

Wat ik graag wil is:
Ik heb een variabele potmeter die 1 tot 4,8v geeft deze wil ik graag aansluiten op een analoge ingang 1 van de nodo.
Op het moment dat ik dan bijv. userevent 1,1 gebruik moet een analoge uitgang (pwm) dezelfde waarde geven. 1 tot 4,8v
Maar op het moment dat ik bijv userevent 1,2 gebruik moet de analoge uitgang (pwm) een mindere waarde geven bijv. 1 tot 2,4v
een soort van spanningsdeler dus. de exacte deel waarde weet ik niet maar dat zal wel in te stellen zijn.

is dit mogelijk?

Het mooiste zou zijn als er een plugin gemaakt kon worden van de PID library
Op die manier kan het uitgaande signaal ook nog afhankelijk zijn van een 2e ingangs sensor. bijv temperatuur, toerental of ampere's

EDIT zie dat er een PID plugin is maar de link is dood... :mrgreen:

Hopelijk kan iemand me hierbij helpen want van arduino programeren weet ik niet veel.

Groeten Dennis

Het blijft ook vrij stil van de andere.

Fijne vakantie!!!
