If it's too small, or too big, it'll be a problem. Hook up the switch diagonally, then it will be correct no matter which way it's in. If the (small, square, momentary & 'tactile') switch is put in 90 degrees off, then it will always be closed, no matter if you are pushing the button or not. The tactile switches used in the tutorial have to be turned the right way to work so that could be the issue. This should print the state of the button so you can check to be sure it's working correctly(should change from 'button released' to 'button pressed' when you press the button.

read the state of the pushbutton value:Īfter uploading that sketch open Tools > Serial Monitor and make sure 9600 baud is selected in the menu at the bottom right of the window. initialize the pushbutton pin as an input: Int buttonState = 0 // variable for reading the pushbutton status

Try this sketch: const int buttonPin = 2 // the number of the pushbutton pinĬonst int ledPin = 13 // the number of the LED pin The button was oriented correctly before as well so it wasn't that. Maybe something wonky with the breadboard or some kind of interference I don't understand. I ended up getting it to work by shifting the whole circuit over on the breadboard so I'm not sure what exactly was going on. The other examples up to now have worked fine and in the blink one the LED goes completely off and on so I'm not sure what's going on here.ĭoes anybody have any ideas? Sorry, I'm fairly new to electronics and still probably considered a beginner in programming.Įdit: Ok guys thanks for the replies. I tried it with an external LED attached to pin 13 as well as using different pins as an output and it still does the same thing.

It took me a while to even notice that it was actually getting brighter when I pushed the button.

The code and circuit is exactly as it appears on the website but when I upload it to the Arduino, the LED is always on but gets slightly brighter when I push the button. I encountered a problem when I got to this one Hey, I got an Arduino UNO and I've been going through the example builds that come with the IDE to understand the basics.
