Nice and easy explanation

[@EDISON_SCIENCE_CORNER]

Thanks 🙏

[@drelectronics13]

Nice and easy explanation, will use in future projects

Good idea

Thanks for sharing
can you help me to make circuit schematics and code
I want to read voltage with an isolated ground
Mine setup is 4x 12v battery with 4x solar controllers with 1x Esp32 and 2x ADS1115

[@EDISON_SCIENCE_CORNER]

Possible

[@Edmorbus]

Please help me with this @@EDISON_SCIENCE_CORNER

The problem with this method is when u press 2 switch in same time the analog value will completely change.. so it's a bad idea to use this type of method in a controller..

[@EDISON_SCIENCE_CORNER]

You can't normally use that. But in critical cases we can adapt this type of hacks without any problem . By the way if want want use two buttons at a time that is also possible by just reading the analog values at the time of two button push.

@@EDISON_SCIENCE_CORNER exactly, you can setup if statements for all the permutations

[@EDISON_SCIENCE_CORNER]

Yes a user can alter accordingly

In this way you not only make the code complicated but also cause a noticeable delay , false reading etc.. this technique not good for a controller but for other such small applications it's a fantastic trick

[@drfrancintosh]

Actually, if you use an R2R resistor ladder that should work fine… The each button would be a power of two resistance instead of a multiple of two and in that way, you can push two buttons at the same time and read the binary values in different statements. Although I am interested in the performance lag or the latency of reading the deck in real time.
