a temperature sensor was actually my first use of it (and i will continue to build a couple as remote sensors) - basically, i&#x27;ve been adding more and more sensors just to see how much it could take.<p>now, i&#x27;m having to build out PCB&#x27;s to support everything (including the voltage regulators to 3.3v and 5v), as i&#x27;ve outgrown breadboards.
