In this article, you’ll learn how to connect a push-button to an Arduino board. You’ll also see how to interact with a push-button using code. You’ll make basic connections using jumper wires and a resistor (including diagrams), and how to get the current state of a push-button ...
准备做一个类似游戏厅里用的投币器,先用PushButton模拟投币环境,当按下开关时,Arduino发送数值0到Flash,不按时为1。 在flash中设定,当读取到的数值为1时,影片剪辑ball透明度为100,读取到的数值为0时,影片剪辑ball透明度为0。 此时遇到以下问题:在flash中读取到了由arduino传来的0和1,但透明度无法改变。 下面是...
