I see in the documentation for WLED that I can use a potentiometer as an Analog Button to control brightness. However I can’t find much in the way of examples or documentation on the topic. Specifically what I’d like to know is how to wire it up and which pin to connect it to. I’d think I connect…

I think I’m having a similar confusion as Fuzzball. I know how to wire a pot, but I’m not sure how to configure WLED to use the pot for brightness. I see that in the “LED Preferences” I can set the pin number for the buttons and use the drop-down menu to set it to “Analog”, but what pin number do …

There are usermods available that use external hardware to handle specific tasks. Perhaps there is a usermod that handles your needs perfectly, or close enough, or maybe just needs a little customization to work.

For ESP8266 assign any unused GPIO. The code will still use A0 (or ADC0) on ESP8266.

Thank you! I actually found this out while rummaging in the code after being pointed to usermods by huggy. I had tried configuring it before, but when I applied 3.3V or 0V to the A0 pin, I got the same result (depending on if it was set to analog or analog inverted). But now that I connected an actu…

Consider me stupid (no really, please do) What is the setup exactly. For a n00b like I can;t make heads or tails of these replies a potentiometer has 3 pins : which pins do I need to connect? to which GPIO pins do these connectors to be connectod to? what type of potentiometer is recommended, 1k …

Numbering your bullets… See Analog button to control brightness? - #2 by tonyno Any of your ESPs analog inputs. Almost anything. I’d use 10k. Doesn’t matter. Correct.

Apologies for my late reaction. But thanks for the reply and the info, it is very helpfull

I cannot turn off the strip via console or with api (& T = 2) because the analog button turns on again immediately. in the same way if I use an analog button to control the primary color (value 200) then I will no longer be able to change the color from the computer or app, because the analog button…

[image] da85wled: Where am I wrong? Nowhere! The analog pot overrules the app control. By default, the brightness potentiometer will turn the lights off if adjusted to either the minimum or maximum adjustment. You might be able to add in a SPST switch to disconnect the pot from ADC0 to restor…

Pot ends to 3.3v and ground, center to an analog input.

All pin numbers in the UI are GPIO.
