02 : Delays

Goal: Blinking "Hello World" display.

Delay block pauses the program for the amount of time specified as parameter. There are two types of delay blocks - the millisecond delay block and the micro second delay block.

Click on the millisecond delay block. Then click on the red arrow on the right hand side of the block that just appeared.

Now, on the the second row of buttons that just popped up, click on the "#". This is how you send a constant value as a parameter.

A box with a zero should have attached itself to the right side of the delay box. Type 1000 into it. This will tell the robot to wait one second (1000 ms) before executing any other operations.

The below program will blink the "Hello World" display 2 times with a delay of 1 second in between.

Run the program and check your results.

Activity: Try Microsecond delay block with the same values. Observe the difference in the delay.
