hello guys i'm looking to create this lamp project,(Satisfying LED Mood Lamp - 3D Printing and Arduino DIY - YouTube) i would like to know how to add a potentiometer to manual adjust the brightness of the entire led strip. thank you!
What type of led strip?
Check a tutorial on how to read the value of potentiometer, there are zillions on line, and then read this value and depending on the type of strip and library you use to drive it, use the value to set the brightness
For example with the fastLed library , there is a setBrightness method that will drive the whole strip
