A/C Great thread idea, just what I need.

I really like 10K NTC thermisters for temp. sensors, they are cheap, stable & don't jump around.

I have several sketches running on Arduino Uno, reading multiple analog sensors (pots & 10K NTC thermisters) & controlling multiple relays.

These 16-channel multiplexor breakout boards are very handy, as I quickly ran out of analog input pins:

8-Channel relay module, Arduino can provide enough current to energize these from digital pins and these can then control SSR's

Good stable pots for setting analog levels (the cheap ones are junk)
