Good evening, Please could you give a more specific link to the Hi voltage PSU. When I have tried to search ebay, all I end up with is 6000V PSU's .Ta
Hi guys, I see that you use any current limiting resistors in series between the micro and the 7 seg. I was taught that this was good practise and see that the resistors are missing on a few of the mux' ing Instructable. Why?
Hi guys, I see that in this Instructable and a few others , on mux'ing, there are no current limiting resistors between the micro and the display. I have thought that that it was good engineering practice to pretect the micro with resistors, should something go wrong. Comments please.
