Hi,
I am currently brainstorming ideas for a light effect to put into the spokes of my mountain bike wheels, essentially i want to be able to do something like those led pattern fans. I already got the pattern down and know all that, the only issue so far has been setting up a stable clock so to speak. for example its no good to have words displaying if they spin as fast as the wheels.
Anyway, just now it occured to me, i could put sensors along the spokes and have them detect for infrared light, to establish that that point in time the whole thing is upright, and i could have the pattern adjust to display upright based on when a sensor detects infrared light, no problems.
What im asing about is what would be the best way to do this?
Should i use a photoresistor with an infrared filter (to block out everything but infrared), or are there specially designed infrared sensitive resistors or cheap sensors that change resistance and so fourth, when exposed to infrared light? the aim is to situate a laser or infrared led to activate the LED's by triggering a sensor, and this would be done for like 10-15 sensors along the wheel. The intention here is to only use said effects at night.
ANyway, what would be the best way to trigger the sensor? laser? high powered LED? and what kind of sensor could i use? would a photoresistor work?
