So here is my idea. Currently I use java to control ALLOT of LPT relay boards in my home automation project. I am looking at the Arduino Ethernet board to create a relay board that can control 32 relays and between 20-32 inputs. Now I know the unit I'm looking at has only 14 digital outputs.
Being a beginner at electronics and just mastered the simple LPT relay board I need some answers on the following:
- Will the Arduino work for what I'm trying to do? (Use Jave to control the outside world)
- How many relays would I be able to control?
- How many inputs would I be able to read? (Mostly switches to indicate a on/off)
- If this is possible, could someone point me to a VERY DETAILED schematic or tutorial to get me started.
Thanks in advance.
