Recall the last time you tried to dim an LED using pulse width modulation. ... The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 ...

LED dimmers are like $3 on AliExpress, but yeah that's much more than a potentiometer. On the other hand they handle 12-24V and like 6A of current. You can sink that kind of power into a pot.

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a. ... You will need an Arduino board, a ...

The transfer function of LED current to potentiometer resistance is basically linear, except at very low dimming. The maximum current is limited to 1 A because of the internal 2.5 V clamp shown in ...
