I would like to know and need help from you guys on how to build (wire up ) a automatic dimmer circuit to control multiplexed 5 individual common anode display and or mini bullet type incandescent bulbs ?
We are not a free electronic design service. Have you tried searching the internet for what you need? What is your electronic experience level? Are you able to design circuits yourself?I would like to know and need help from you guys on how to build (wire up ) a automatic dimmer circuit to control multiplexed 5 individual common anode display and or mini bullet type incandescent bulbs ?
Did you draw the schematic of the display? It looks completely incorrect. All the anodes of the LED displays are connected to 5 volts. The segments of U1 and U2 are the only ones that show multiplexing. The segments of U3-U5 are hardwired to ground with no current limiting resistors. Then there are 5 PNP transistors (Q1-Q5) that are wired across the 5 volt supply and the emitters are connected to ground. WTH.I hope I am making sense
