Wait Until Blocks (EV3)

output-onlinepngtools__231_.png  These blocks works for EV3 Robot! 

The Wait Until block pauses program execution until a specific event occurs. There are multiple variations for this block, each for a specific sensor.

It's important to note that this block only pauses the program from executing the next commands, until the event has occurred, not the robot itself.

We have included examples of sensor-related events that will cause the robot to stop.

Note: EV3 Robot is featured in several courses, and its Gyro sensor behaves differently in each course.

Legacy Cyber Robotics 101

New Cyber Robotics 101/Code Farm

 

Legacy Cyber Robotics 101 (Desert theme; fully yellow Wait blocks)

  • Wait until the color sensor detects the color Blue (Color ID = 2)

  • Wait until the left motor encoder count is over 100

  • Wait until the ultrasonic sensor detects an obstacle at a distance of less than 250 cm.

  • Wait until the touch sensor is pressed

  • Wait until the gyro sensor turns more than -90 degrees (to the right)

 

New Cyber Robotics 101 / Code Farm (Farm theme; yellow+green blocks)

  • Wait until the color sensor detects the color Blue (using Color Name method)
