Problems during the lab
When I press the push button, the circle won't disappear
I think this is a problem of poor wiring. The flickering of dots on the image means the outcome of the push button in Arduino is keeping changing between 0 and 1. After I keep pressing the button without releasing it, the circle won't flash since the status is "1".
