cnc lamp controller
I needed a controller for the safety lamp of my cnc under construction, looking on the net I had not found anything that interested me / was compatible with my motherboard, hence the decision to build it. Arduino first of all performs a count up to 9 via the display (initialization), then, based on the readings of the analog signals, the Arduino switches on / off the selected relays (based on the low, high signals). The display shows the number of the active port (1,2,3, only 1 is on at a time).
As you can see it is a fairly simple system, now if you are wondering why the circuit is made on millefori it is because I forgot to attach the file of the pcb tracks (what an idiot I am :)
At least I'm happy that everything works as it should. Now I will reorder the pcb complete with tracks since I need another one :) (ah, of course everything works)
