I´m a newbie with arduino and eletronics, but I must say that after I entered this new "world" or arduino, i realize I could bring toghether some of my wanna do projects. I´ve recently aquired an Arduino UNO, in order to develop a aquarium monitor system, like many did in other sites and this forum.
I´m having issues now with the capabilities of arduino, and if it will be able to deal with my sensors. My question really at this point is related to the capacity of arduino and it´s pins.
My project involves:
1) LCD Module with 4 switches keypad. 2) RTC Module 3) Ethernet and SD Shield, to access information on web and store sensor parameters on SD. 4) 1 Temperature Sensor Probe 5) 1 PH Probe 6) 2 relay modules, to access hardware (pumps and so) 7) dimmable control for leds, moonphase and so.
Can an arduino UNO support all this connections at once? Or will I run out of pins and need to do a multiplex?
Any help will be great
