WebSep 12, 2024 · In the old days we made LEDs flash with only a single UJT transistor, or 2 bipolars. Not everything needs a micro. If it's a flashing LED (i.e. an LED with the flashing electronics embedded) just change it. Otherwise you might need to add a monostable (one or two BJTs, or an NE555). WebSep 4, 2006 · The "logic level" ones are also good for 9V. as long as you can be sure the voltage never exceeds 10V. You can use a. 555 to switch MOSFETs. Also consider 4000B series logic - good for all voltages 4.5 to 15. volts. 74C series logic is also good for at least the 4.5-12V range, maybe 15.
WebWiring LEDs in parallel allows many LEDs to share just one low voltage power supply. We could take those same four 3V LEDs and wire them in parallel to a smaller power supply, say two AA batteries putting out a total of 3V and each of the LEDs would get the 3V they need. In short, wiring in series divides the total power supply between the LEDs. Web13 hours ago · Updated: Apr 14, 2024 / 06:37 AM CDT. TOPEKA, Kan.
