Ez Robot community I wanted to introduce my latest application of this system. Some members hear already know I keep two salt water aquariums one coral which unfortunately died off and my predator tank. Sea life needs delicate balance maintained in their little ecosystem. Things like light spectrum , temperature, ph balance , current of water , nitrate and ammonia levels and calcium levels. These things take a practiced hand to maintain. I am building a new system and using ez b to monitor salinity, nitrates and ammonia, temp , water current flow and the ph. The ADC ports are useful for these and EZ board can control the current and switching to a backup power supply ( a apc for computers inside the cabinet to keep ezb and pumps powered). Also the ezb can turn on and off night , morning , day , and evening lighting settings. With a custom injection device im designing ezb can provide nutrients , calcium and even medicine if levels are out of wack. I started the build today and I am very excited!
That's fair enough, maybe I'm thinking of AC? I know I was taught not to do it when I did my C&G2390/2391.
AC you dont really need to twist the wires.but you should always keep low voltage wire from AC high voltage wires to reduce any noise that can reset the microcontroller or use shielded cable another reason why network cable uses shield cable to block AC sinewave hum AC is a pulsating sinewave voltage and thats where you get noise or (hum)
JOSH i dont know if you get a low cost idea for reading temperature of the tank but ebay has them low cost $1.50 to $3 it what i paid for mine for a set of 2,i bought 5 sets from different bids only need a 10k resistor and analog port ,they are waterproof,and will need more,since i have 6 tanks so far and 3 gecko cages that needs 2 of them ,plus incubator setup
arduino thermistor probe
10k resistor should have a pot ,makes it easy to calibrate it,like 9.1 k and 2 k pot ,this way you have a range of 9.1 k at the lowest and 11.1 k at the highest adjustment
IF you want it super stable,i have ideas for it,but for EZB its not needed
In my background of telephony twisting wire is really important for all the reasons FRED(robotmaker)
indentified. and all his other suggestions are valid!
Ok i updated software , one of my ezb had a problem so I swapped it out. https://www.youtube.com/watch?v=d-ld3Ukcz5k&feature=youtube_gdata_player

After I did the firmware update I had a issue with my pc. After reboot it said "chassis intruded fatal error". The best I can understand is its a jumper that a switch can be attached to to indicate the case is open. I can pull the cmos battery and it starts fine with default cmos settings but once I power it down and back up it says chassis intruded fatal error and u get pretty upset. Any help , my board is M4A88T-I Deluxe Asus , its been working perfect for a while till I i put the motherboard in a case and now it did this. [
check your battery,then update the bios from website
If you don't have it, download the Mobo manual from the manufacturer here, in it will show the jumpers. Failing that, the bios should have an option to disable the alert.
It looks to be in the bottom right of the mobo, next to the clear RTC.
And use the clear CMOS jumper rather than pulling the battery, it's easier
