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!
The diode goes across the coil,if you look on the internet you will see it on the coil reason is that its a inductive type ,and when you apply power and then remove power the energy builds up and cause a spike called INDUCTIVE KICKBACK ,and then transistor get fried What the diod does it clamps the voltage so no KICKBACK
CATHODE IS V+ on the coil and anode is the transistor emitter
Inductive is not a lamp,its resistance load
Inductive is motors,coils and solenoids and transfomers
couple of other points on using power transistors you should have a 100k to gound just incase for false triggering,what is does it keeps it low till you get a high signal to turn it on microprocessor like used on EZB can false triggered can set it up in a script code to stay low until it needed,but can still false trigger also lower the base turn resistor to 470 ohms can help too (2 1 k in parallel) will work
FISH LOOKS REAL GOOD ALSO
I love to have a stingray like my friend thats a actor has in his 6 foot tank
I picked up colored set of tape to mark and identify each type of connection. I will probably use white for 110v AC , yellow for 12v , and red for 5v. It would have cost me 40 dollars or more to get multicolor crimp connects.looks good so far,on the multicolor crimps i get them from digikey very cheap and fast shipping
Damn. All you need now is a magnet based cleaner with x/y track that cleans the front glass every hour. It could run back and forth then lower its self and do-it again. I know those magnet glass cleaners cant be that much.
IROBOT sells a window cleaning robot
@robotmaker on a different thread, Your told me your name was FRED as is my robot..Friendly Robotic Entertainment Droid! Imitation is the sincerist form of flattery
Giant update! My roommate Dan wheaton helped me with rewiring the switches and relays for negative pulse to trip relays. This is because the tip120 Darlington opens to ground not positive.
This ezb powered on the first time. Blinking status light and no Bluetooth light but I have not updated the firmware yet. Next step is to start running the 110v power wires to the relays
taking a break for dinner. I used plenty of zipties to clean up the wiring and drilled holes in the case where I used zipties to hold them down directly to the bottom of the case.
