Hi i made this project on wokwi( mover no eliminar - Wokwi ESP32, STM32, Arduino Simulator ) and i want all the buttons on the same pin but i am so confuse how to do it. i try to learn following some tutorials online adapting the same wiring schematic on the tutorials to my project and nothing any he…

Hello cuasitos Post the current sketch and schematic to see how we can help.

[image] cuasitos: i want all the buttons on the same pin You can use an analog input pin and a voltage divider. Examples [image] [image]

Hi i am trying to connect multiple buttons single pin on wokwi for later transfer to a physical way. My project is https://wokwi.com/projects/416105201673194497 but when i trying to load the project serial shows on cycle in Spanish because is my main language (valor analogico:0 and valor no reconoc…

From wokwi: warning Wokwi only has a very basic analog circuit simulation. You won't be able to use resistors together with analog components (e.g. potentiometer or NTC temperature sensor). You can still use the resistors as external pull-up/pull-down resistors. This is your problem. :wink:

What is wrong is you asking Wokwi to simulate something that is bad practice and cause lots of problems. If you are short on GPIO pins, you can reduce the number of pins needed by arranging your switches in a matrix.

[image] cuasitos: My project is multiple buttons single pin This could be interesting I have no clue on how to simulate with Wok Wi! so I will assume you have an analog pin. free. This will allow you read several buttons but the limit is about 5. [image] This approach works by connecting…

on that case maybe mi circuit is fine but wokwi can simulated?

Of course, in wokwi you can't simulate this type of analog circuit.

You can use an analog input pin and a voltage divider.
