Hello guys,
I have small device with buzzer I need remove it and try read it/detect with arduino.
I try read analog input with positive buzzer wire connected to digital pin. But without any results.
Please its there any solution how to do it?
Thank you.
Welcome aboard...
What devices are you trying to use...?
Without more information about what exactly you are doing and what devices other than an Arduino you're using, maybe we could make some suggestions.
Take a few and check this out ...
Im sorry.
I want use arduino uno.
The device which use buzzer is smal coffee machine. When coffee is ready buzzer start beeping. Its 5v buzzer.
I want this remove buzzer and replace it with arduino uno. I need detect with arduino, voltage or some data from buzzer cables going from machine.
I was trying detect it with analog input, but I cant get any data from it, everytime its zero.
I use only simple analogRead(A0) with print to serial monitor.
You need to know what kind of signal the buzzer has. If you can measure the signal with a scope, that would tell you. Most of these are just driven by a digital signal, my pc has something like it.
Why would you want to use an analog input on something that is pretty much digital?
There is someone else dealing with a coffee machine and had some issues with a proper ground.
Do you have the tools/experience to find your way around in there?
You will be exposed to the mains voltages...
What is the end product ... once you detect this, then what do you need the Arduino to do?
You will need to make sure you have a 'common' between the coffee maker and the Arduino or you probably won't see a signal change...
Good luck
