BS2 Code for motion LED project

stuartX · 2012-02-26 11:09

I'm creating a project that LED striplights are trigger by motion sensors. I have the code posted below. The problem I'm seeing is that it seems that when one sensor is triggered to light the LEDs and if a second sensor is triggered within the same time frame of the first sensor being triggered, the second motion is ignored until first sensor is off.
What I would like to happen is if one sensor is triggered, it lights that set of leds and at the same time if a second sensor is triggered it will in addition light the second set of leds at the same time.

The problem you are experiencing is related to the fact that the stamp can only do one thing at a time and your pauses sre stopping any other actions. You need to creat a loop that tests for all the sensors and then turns on the appropriate leds then loops for maybe 1/10th the time, increments a variable then loops.

thank you for your response. I'll give it a shot. But I assume that the propeller can perform this function with no problem?

The propeller can certainly handle the code, but you could also still use a BS2 and once sensing an input, send an output pulse to a 555 timer circuit to take care of the LED on timing.

That sounds like an idea. I would have to test it to the gate of my Mosfets.
would I connect the output pin of the stamp to the trigger?
