Hi, I would need a switch that provides multiple positions, but that outputs an PWM value that can be read just by using only one pin of the Arduino. I've seen this: https://www.dfrobot.com/wiki/index.php/Rotary_Switch_Module_V1_(SKU:SEN0156)
The problem is that the shipping costs is higher than the price of the swith itself. I would like to know if there is any alternative that can be send with lower shipping costs or even free like some things on AliExpress.
I've found many rotary switches, that have multiple outpus, but I don't se those output pins fitting on a breadborad, nor I have no idea of how converting so many pins into just only one, although I've read that resistors need to be used for that. I would appreciate any help that you could give to me.
My project is just as simple as use the switch to select a different song to play every time. Is something I want to show to my toddler.
Thanks in advance.
