I have a problem with one part of my PhD research methodology. To be more precise, I need to be able to record the response time and hit rate of participants to a stimulus. Ideally, I would like to be able to preset a system to flash a single LED for a variable order (LED flash should be pre-set to alternate and not be uniform), and the participants would press a micro-switch to confirm the flash. The system would then give data back to the researcher for response time in milliseconds for all the observations and the hit rate for successful observations. The participants would have no interaction with the set up, and only have access to the response micro-switch and LED.
At first I thought that the Arduino was the way to go; however, after I came across the Duinomite-Mega that used Basic, and could display much more information on a monitor, I had a change of heart. So, do any of you know if this platform would be able to perform the task I mentioned above, and if it can, do you know how to do it? |

Hi Shinddz,
yes this is right task for MM. Because MM support interrupts, the the core routine could be just a few lines of code long. Of course if you want to have all bell and whistles it can take some more time but with MM Basic this will be very very simple task.

Thanks for the message boss. I'm glad, this platform will work. Sometimes you can be spoilt with too much choice. I can't believe that I will be using Basic again. I havn't used that from I was a young child. It would be handy if someone could give me a few tips to start me off in in the right direction. |

Hi Shindzz,
can you send me more information and I think I can help you with the programm design. Believe me or not I'm one who almost have the experience with the same equipment from the rehab centre. They are assesing heart attack and stroke survivors in the same way before they give them the driving license back. |

You should also be able to perform this task using a the much cheaper and easer to prototype PICAXE chip. This is also programmed in Basic and you could display results on a LCD or simply send data to a PC using a USB adaptor cable. However, the Maximite would be a much better long-term research tool. |

Bugs 2, thanks for that point; however, I'm sure there are a number of possibilities I could have used. I had to make a final decision, so I sent my order to my university last night. Besides, the University gives us some money to buy equipment.
boss, the test will be entirely set up by the researcher before the test begins. The participant will be only aware of a micro-switch and a single LED. The tests will be approximately 3 minutes in duration, and the LED flashes will always total the same amount per test, but the intervals between flashes will range between 3 and 5 seconds, either randomly or specifically ordered in a given sequence that would change with every test. The LED will stay illuminated for 1 second, and the participant will be able to respond to it between 500 - 2500 ms from the stimulus onset; after the LED has been responded to, it should extinguish immediately before it completes its normal 1 second burn time. After the test, the researcher will be given a breakdown of response times in milliseconds and the number of successful hits (hit rate).
If you think you can help with that, I will be extremely grateful. |

Hi Shindzz,
perfect, the numbers were what I was asking for, I'll try to write and test the code during weekend. I'm working for "Stroke Association" and the first time I can spend with this task is Sunday.

Hi boss,
If you can do that for me I will be over the moon. You will be saving me a considerable amount of time, which should allow me to begin primary data collection sooner. When you're finished PM me your real name, and I'll be sure to formally acknowledge you for your help to this project, in the forward of the printed Thesis.
Regards,
Shindzz. |

Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
