Hi I'm new to this forum, and automation in general. I hope some of you would be able to help me out a bit.
I am planning to use my Raspberry Pi to control a brewing system. The brewing system is in a planning state, but I have already made some observations of what the control system should be able to do:
Control 3 SSR's
Read temperature from one or two DS18B20 temperature sensors.
Led display to show some simple status (temperature etc.)
Some buttons for input
Wifi networking (usb stick) to show status and control via web browser
PC-speaker (or something else) to give alarm at set intervals
I have no soldiering skills, and would like to soldier as little as possible. I plan to program the system in Ruby.
Is it possible to connect all this to my Raspberry Pi, and if so, what would be the best way to do it? I imagine I would need to buy some external card i can connect all to, and connect the card to the Pi with USB.
