Can someone help me out?
I want to make a simple LED meter (VU?) that comprises of 5 LEDs, 2 green, 2 yellow, and 1 red, voltages at 2.2 and 2.3 volts.
I need to know what resistor values i would need. This circuit does not use any chips or transistors (i have seen the kit but no schematic)
all it uses are LEDs, resistors, and a diode, a capacitor too.
Its use wil be for adding into some speakers, or on the front panel of a pc to show sound level, and I really want it simple as possible, no chips or transistors (I cant get them easily), resistors and LED's I can get easily tho. and the kit i have seen online only uses them and a diode and cap.
Can someone throw up a diagram and list suitable resistors for such a thing please?
i am still learning this stuff and this will help.
