One picture shows a green circuit board with an Arduino mini pro with 3 connections to each meter and a cable going somewhere else. The 6 header pins on the Arduino are to program it through a cheap FTDI type programmer.
Did you acquire this all as a complete working system or who put it all together? If you bought it online, can you include a link to the product page?
To me, it looks like at least all the hardware is there. If someone has already gone that far, then I would also imagine some software is there as well.
What is at the other end of that cable which has 4 wires (black,red,yellow,white) ? Can you include a picture of what ever is there?
The 3 switches you mentioned in your first post. Are they already mounted on this panel?
Is some sort of sound unit (say SDCard player module with loud speaker ) also included with this kit ?
It could be (although I’m not suggesting that you try it yet) that you simply attach it to a power supply and it will already do something like go through a test routine.
Once it is clear what is already there, then the next step is determining what has to be done additionally for it to meet your requirements.
- I’ve just noticed that the there is an unconnected tab on the back of each meter. This would appear to be one of the coil connections (if those are really conventional analog meters). In that case, maybe only the panel meter backlights are active.
- Is the picture of the plutonium chamber meter from the exact kit you have or is it from another source? It may be that the 100uA full scale deflection does not apply to your meters.
