Re: Questions by Artist on VEX Programing

The random number thing was covered pretty well - just do math on a number and pick one of the digits to key on. I'm not sure exactly how you intend to show Video A instead of B or C or D - i.e., how do you activate a video - but in EasyC, once you select which video to show, you simply activate a specific digital output to play it. In other words, let's say you had five videos on DVD, and five DVD players - to play video 1, connect a relay to digital output 1, have that relay simulate pressing the Play button. And so on. Expensive and cumbersome, tho. The real issue comes down to figuring out a way to store and play different videos. However you'd do it manually, use the digital outputs to automate. Answer the first part and we can help figure out the second part. Good luck, Don Alternatively, let's say you have five videos on a c |

Re: Questions by Artist on VEX Programing
One thing you could do to solve the DVD problem is to have a servo like miketwalker said, but instead of hitting the play button, push the next button. The way it would need to be, on the dvd is to has alternating chapters of ridiculously "background" music and then the speech. then having a counter for each chapter and when it reaches the maximum it would some how reset the dvd player.
This sounds like a cool and different way to use the vex system could you post a pic of the final product when you are done? |
