I am just starting with arduino and programming. Reason why is , my brother ask me would be possible to make his house lighting smart. So I started google it and I found lots of very expensive sollutions like KNX or EIB witch we couldn't afford simply because of the price. Than I found arduino. I like the idea and I would like to lern the coding an more about the electronics which I will do.
At the moment my brother has to start doing a wiring and we are bit under the pressure. Idea is just for start to control 16 outputs using just 5 push buttons. I have everything connected on my bradboard.
I have 3,2-3,5V LED on 5V outputs, I have counted that 850 resitors should be used. I have used 1k resistor for each LED
buttons have 5V on one leg and inputs to the arduino wit 10k pull down resistor each on other leg of the pushbutton.
Is it possible to switch one button betwen let say 3 outputs? I was thinking to use buttonPushCounter and button Status. I don't know yet how to make the buttonPushCounter for more than on button.
Hope it is understandable what I was trying to explain. I am sorry for my writng I am not English
Thank you for any suggestionss.
