等待指令可以讓機器人依據某個條件先感測週遭環境而後再繼續動作.以滑桿或輸入觸發值並與感應器數值相較來作為程式繼續執行與否.
This block lets your robot sense its environment for a certain condition before it continues. Use the slider or type in a value to set a trigger point so that the program continues when sensor values are below or above it.

1. 在等待指令的右上角標示出所連結的輸入端.視需要可以參數面板來更改輸入端.
   The number or letter at the top right corner of the Wait block shows the port the block is monitoring. The configuration panel, which is described below, will let you change ports if necessary.
2. 假設等待的是光源,聲控,超音波感應器.這個圖示會將觸發值分等來呈現.越亮麗的色彩表示越高的觸發值.如果等待的是觸控感應器.則會出現觸控感應器用來處發指令繼續執行的狀態(觸碰,按下,或是放開).
   If you have chosen to wait for a light, sound, or ultrasonic sensor, this icon indicates at what level the trigger point is set; the more colored bars displayed, the higher the trigger point. If you have chosen to wait for a touch sensor, the icon will display the touch sensor condition (bumped, pressed, or released) that will trigger the block and allow the program to move on.
