airbrush said:This is where i measured the voltages from...i guess i'm not sure what you mean by measuring 'across' the resistor then?? I assumed the 5.36 value here is measuring across the resistor :? ...sorry i'm a noob, can you tell
**broken link removed**
The capacitor is cheap, simple and is recommended. Use it on a second circuit if the 1st one without the capacitor blows-up!airbrush said:there is another capacitor in there the other didnt have (0.1uF)...is this necessary for this to work properly
audioguru said:I see 10 LEDs but the circuit has only 2. What did you do? Make a bunch of these circuits?
each color is on a seperate dimmer...they are wired in parallel series of 2leds
I would take the two green LEDs with their 120 ohm current-limiting resistor, connect them to my variable voltage supply then turn down the voltage until they were off. Then I would set the circuit's minimum voltage to be a little less.
I'm not sure what you mean by "connect them to my variable voltage supply" ?? I have them hooked up as shown in the schematic...just the greens ones dont dim off when the dimmer is at its minimum
You can reduce the value of the 620 ohm resistor like this:
audioguru said:Yes, change the resistor until the LEDs are dimmed enough.
Are you connecting LEDs in parallel? You shouldn't because then they would have different brighness levels as your display shows. Also, with LEDs in parallel then they share the current and are half as bright as they should be. Do it this way:
