  • Anyone know how long the data line can be before it starts running into trouble? Looking to run it using three wires (gnd, +5v, and data), over some moderately long distances (25-35 feet or so).

  • Sweet. I’m in the (long) process of setting up a planted Aquarium, with high power lights, fertilizer, and CO2 injection. PH controlled CO2 injection is the best way to go, but the controllers are $200+. But with this and an ATmega328 chip, I can do it for half the cost!

No public wish lists :(
