I am new to the arduino community. I am currently working in a project involving the arduino mega 2560 R3. I am wondering if it would be able to handle all the components that are planned to connect. These include:
I am aware that for the 12V I'll need an external power supply. Not sure if you'd recommend a particular adapter or if I could just use a converter to 7V-12V. I also have concerns if a 400 tie-points would be able to fit all the connections.
My apologies in advanced if this topic is not in the right board.
You're new and that's okey. However Your words make no sense.
Please grab pen, paper and make a drawing of the build You aim at.
Rule number one: Never think about the controller as a power supply for more then a LED or two.
Rule number two: No voltage higher than 5 volt is handled by the controller. If higher voltages are use some kind of driver is needed.
