Just simply watch the short tutorial. If you would like to use this for a project, these are the instructions: 1. Go onto events. 2. Use the green flag block. 3. Go onto sensing. 4. Get two turn video on/off blocks. 5. Attach one of the video blocks onto the green flag block. 6. Make the remaining turn video on block say turn video off. 7. Go onto control. 8. Get the wait seconds block. 9. Select any number of seconds for the wait seconds block. 10. Press the green flag.
I am sorry there are so many steps. It will be worth it in the end. Thank You
