Has anyone added a float switch to there skimmer cup, to notify you when it is full?
Guys have spoken about it, but not sure how many have actually done it?
I want to mount one to the lid of mine but the problem is I want to still be able to remove the lid easily for cleaning. So any ideas would be appreciated.
Due to the fact that you need to removed the cup and lid for cleaning, doesn't make life easy. ether way, you going to have to remove the switch or put a connection plug on it.
I want the controller to be seperate from the plug and I need Ideas for cabling, I have an 8 channel relay. I would prefer for the relay to be on the controller but that means I need a cable that can handle 220v and has multiple cores.
I'm not 100% sure on what you mean here, Are you trying to isolate the 220V from the Arduino, or just seperate the "parts/devices" in the sense of some space/distance?
I assume you are talking about the latter, it would depend on the design/connection interface of the relay board. If the board has a pin for each relay input then you would have to use a multicore cable, something like they use for running alarm cables, as there is little current, it doesn't have to be thick at all. Otherwise if you want to get fancy you could use a I2C expander to drive the relay board, this way you will only need 4 wires, of which 2 are power supply, this would also only use 2 pins on the arduino board, and can run on the same bus as other I2C devices.
Did anyone else have problems uploading code to the mega2560? I am having a few problems but I think its the bootloader, I am going to try install a new one today.
Any ideas where I can get a box to enclose all this?
