after not using my Arduino for a while, I started doing the project 01 again. The push button is having a strange behavior that I am not able to understand. As far as I can remember, this wasn't happening the first time I did this project.
When I try to build the very first circuit, the push button isn't closing it:
However, if I substitute the push button with a wire in exactly the same pins, in order to discard a problem with the breadboard, it works:
Now to check the push button I just connected it elsewhere in the breadboard... and it also works!
Please help me to figure out what is going wrong here! Why isn't it working on the first case?
thanks a lot for your response, you get my first karma point in this forum.
I tried what you said, but it still isn't working. If I add some male connectors or wires and then connect the switch it works, so I guess the switch has problems to connect in the breadboard in that position.
