Understanding the coil
I'm the first one!
I'm kind of newbie programming with ladder and this drag and drop method. It is clear what a timer and counter is, but what is a coil and how should I use this 'thing', I think that you guys call it contact. 😎
the coil refers to an arduino output for on/off switching
I also wanna know about it, what the purpose of the coil in programming?
and there are types of the coil? and it's possible to do programming without a coil?
