I am building a clock and adding individually controlled LEDs. This is my first arduino project and I am a beginner with working with circuits.
I am using a POT to dim all of the LEDs simultaneously. But when I dim the LEDs some dim quicker than others. All the LEDs are connected to there own digital pin.
I found that the LEDs that are dimming slower are connected to PWM pins.
Is there anyway to make all 10 LEDs dim together.?
Show how you have it all connected.

You can't dim leds that are not connected to pwm pins!

Use a transistor. Like bc337. Connect the transistor's base to a single pwm pin with a 1K resistor. Connect the emitter to ground. Connect the collector to your leds/series resistors.

Totally can if he's using the pot in series with the common and not as an input as your faith in him must've assumed.
Not sure how that's manifesting as current differences.
