Help with Program - Simon Says

ktdid07

Hi, everyone.

I am trying to build a simple Simon Says game with 10VDC lights...you know, like the one you used to have where the game would flash a series of lights at you, and you would repeat the pattern. Correct repetition would earn you points or access to a new level and incorrect repetition would lead to something unpleasant, like a loud buzzer or imminent death. [noparse]:)[/noparse]

Anyway, I was wondering if anybody had some suggestions on programming using PBASIC. I am trying to figure out a "random" pattern generator, and also how to allow the program to interpret the data coming back in.

Can anybody help?? I really appreciate it.

Thanks.

How about:

Make a tight loop with a counter that monitors a switch. This will be the start switch. When the user presses the button, use the counter number as a seed for the RANDOM command. Random isn't really random, if you use the same seed, you will get the same patterns. Using the counter as a seed will make it much more "random".

Nice answer, Jonathan. Base "random" on user input, such as how long they held a button down, or how long it took them to find the right button. I prefer to get new random input every loop instead of using the built-in random generator. Simple timing loops. You'll do the right thing.

BTW, I give out this same problem (program Simon into a BS1) in a course I teach on toy design. It's a great problem, and an opportunity to use 4 pins as both inputs and outputs. That is, light the LED and then monitor its switch with one pin.

Hey, wait, ktdid07, you had better not be a student in my class, soliciting help from all these Basic Stamp gurus in this forum! JK

For truly random effects you need to keep randomizing the seed until the user presses a button…This should happen before each new reseed to keep it true.
