This is a follow up video to my “Building an LM3914 Alternative LED Bar Gauge Circuit” video. (link below). Following a comment from @d4vidd who asked about implementing dot mode (opposed to bar mode) I have made a simple modification to achieve equivalent effect of an LM3914 configured in dot mode.
