ADD also means that it's hard for me to concentrate on several things at the same time and that I get easily distracted and frustrated.OFF-TOPIC:
For example, reading a text (tutorial, post, whatever) that has grammar or spelling errors, use of idiomatic abbrevations irrelevant to the subject such as "u", "r", "wtf", "moar", "plz" and so on,
instantly irritates me, because I think English, as the most widely spoken and a very beatiful language, deserves to be respected and used properly. This irritation fires up the neurons and neurotransmitters, that trigger a defensive state in the brain, because I feel my thoughts need to be protected from the influence of others. If and when differences in opinion are confronted, the brain releases the same chemicals that are used to ensure survival in danger. This causes the more primitive part of the brain to interfere with rational thinking and the limbic system, which makes it hard to process an idea, no matter how valuable it is. Even if the threat comes from harmless things (like what I mentioned above) that we could otherwise agree with or relate to. In a defensive state like this, learning and understanding what I am reading becomes very hard.
And I do know that I myself am not perfect in English, but at least I give it the respect it deserves and try to use it properly. Most of the time I have the dictionary ready in another tab.
And I use it alot.Back to the topic:
I still don't know how many devices the arduino can handle without having a huge delay between requesting an action and the action being performed (Who wants to wait 10 seconds for a light to get on, when you can walk to the switch in that time...). I Just need to know this so I can plan things ahead. For example, at first I'll be using the system in my room only, since I'm underage and living with my parents, but I plan to expand the system. Maybe my mother would let me hook it up to our coffee machine, since the ON-light is broken and we don't have the screwdriver needed to open the case and everyone is too lazy to order one.
So if I'd know that it could handle, say 5 devices, I could figure out the expenses (how many relays I can use per board and so on?).
The hardware page says:
Digital I/O Pins 14 (of which 6 provide PWM output)
Analog Input Pins 6
Does it mean the arduino can handle 14 devices at a time?
PS. I didn't quadruple check every word in the OFF-TOPIC explanation, so slap me with a fish if it seems illogical.
