<Frankly I don't understand the function of the 555> just simply to generate 10 hz led 2/ led 1 -1Hz has no connection to arduino.
any report of inconsistencies or errors is welcome, thank you. On this basis, valuable advice for the sketch to be used and how to set it up are welcome
Cioa late again but with last I really hope so scheme, in a very short time pcb and final testing where I will ask for your contribution.
<To drive the decimal point you need another Arduino output. But 'I'm printed you have it?>
the decimal point or rather two in the sense that each nixia has two left and right points that light up simply by connecting them to ground, in practice I will turn on the point on the right on the second and fourth nixia, the pcb after last nixie connection error is in preparation.<The sketch was designed just to be able to drive the nixie in multiplexer>
Well as soon as I have everything ready I try it, let's keep it as a reference for this forum for any changes / adaptations / Thank you<I'm 4 x 6 = 24 connections> multiple optocouplers. I am waiting for the pcb certainly also not to cause some trouble, there are always the 160Vcc of the nixie.
Surely multiplexing as per your unanimous advice is the chosen path, in fact the pcb has been set up for this.
Now for the first rudimentary tests starting from the sketch posted with the time and date of the NEO regardless of the two hours back we want to start writing a few lines to try to display only the time, first on the nixie? E’ to clean up the sketch will not serve as already said alcul separator only 6 numbers in the format : hhmmss, single separator use dot only second nixia, quarta nixia
