Hello,

I need help on building a circuit to light up LED-s. the LED-s light up with a voltage of 0.7V and each diode lights up with a certian current (first one needs 1mA second one needs 6mA, third again 1mA then 7mA, 2mA, 5mA, 6mA). Can anyone help up?

Thanks in advance.

Hi,

First of all, what is your intent for this? Is this fading application? Secondly, how do you plan of connecting the LEDs. What configuration are you going to use? There are different voltage drops for each LED. Moreover, in the case of different test currents. If you really want to pursue this, you would need a programmable LED Driver.
