as the subject please help me
as the question. please help us.
You need to be a
little lot more specific about your issue. But yes, there are many ways to perform your cryptic task.
so i want to use node-red to trigger function to spin the motor in arduino with any nodes
Do you want my code?
read node_red signal
if node_red signal = high motorspin() ;
if node_red signal = low motorspin() :
void motorspin() if node_red signal = high motor = spin ;
if node_red signal = low motor = stop ;
you mean like that ?
yes, all you need to do is write all the code to get the signal from code red then write the code to put values on that signal then write the code to use that value to turn the motor off and on.
