Will this circuit with 3x LED work?
Picture of the schematic (don't mind the white box at the bottom):
-the power source is 3.7V Li-Ion battery
-the box right next to the battery is a 5V step-up module (this one)
-the resistors are different because the LEDs have different Vf, every one is calculated to limit the current to ~18 mA (with potentiometers at 0)
-all potentiometers are the same with 1K max and 0.05W (I'm not sure if the wattage is enough though)
-the LEDs are all marked as a 20 mA, that's why I limit the current to a safe 18 mA
So what do you think? Will it work? Is there anything that could be made better?
Thanks for all replies!
