Ok, Heres what I want to do. I want to have an LED light everytime it gets a pulse to the circuit. I want 1 blue led to light when its pulsed and 2 white leds to light when its pulsed but I want it to alternate between the two colors when its pulsed. If that seems confusing Ill try to explain it better.
I'm sure there are dozens of ways, but first thought was a 4017, resetting after the second output. The whites should be in series.
what do you mean 'pulsed'? if you mean sending a single electrical signal (like pressing a button) then a simple relay would do.
Something like this? (or from http://www.candysporks.org/~cburnett/forums/alternator/) Basically the PULSE line is the source of your pulse. First pulse turns on T1 and subsequently D1 (blue LED). Second pulse turns on T2 and subsequently D2 and D3 (white LEDs). Where R1, R2, and R3 are appropriately sized for each LED. So with each pulse you get: blue -> white -> blue -> white -> etc.
Even easier: My design for alternating IDE led's but you can connect it to anything. http://www.zapwizard.com/led_Changer
Hang about, Zap, your circuit lights colour A on high input (pulse), colour B on low input (no pulse). I thought we were after: ON - OFF - ON - OFF - ON... bloo-off-whites-off-bloo... 4017 rules OK (come on, DETN8R, I've only got a Ph.D in reading my wife's mind)
Ok, I plan on modding this circuit into a mouse, more specifically the Nostromo N30. I won this as a door prize at a lan and I dont really like the vibrations from the motor inside and I hooked up an LED to the motors plug and the led would flash rather than have the mouse vibrate i wanted to have a few LEDs flash. I plan on removing the motor inside and maybe even enlongating the mouse somehow.
Well to define *exactly* how fast it can go is not clear-cut. So make a guess as to what you think it will be. 100 times a second? 1000? 1 million? More than a 100 and you won't be able to notice that they are flashing, but will be on and somwhat dim. The circuit should be able to handle minimally several 1000 times a second. Note: The vibration frequency does not equal the frequency applied to the motor since 99% of vibrators have an imblanced weight at the end of the motor to merely shake. You really didn't answer my question and I know nothing of the N30....
You want something that will make the faster pulses less fast? As in like you want to make two pulses become one pulse? In order to answer you question, you *must* answer these questions: How fast does <insert source here> flash? How fast do you want your LEDs to flash?
Thats the thing That I dont know. The Motor inside can shake extremely fast and when I have and LED in ther while the motor is on and shaking fast the LED appears to be lit but at times when the vibrations are less fast I can clearly see the LED flash. as for the Second question, I would just like them to flash fastly but noticeably.
You can use the 4017 and use the /10 output to get a 1:10 reduction. You could use a binary counter to get 1:2, 1:4, 1:8, or 1:16 reduction. In conjunction iwth the 4017, you can get just about any reduction.
The only difference is the quantity of flip flops and the lack of a preset pin, but neither of these differences matter.
i'm not quite sure what you talk about, but normally the motors rhat makes vibration has constant power.. it's the off-centered weight on the motor that makes the vibrations, not pulses to the motor...
It should be pulsed. It's the sudden acceleration of the lopsided vibrator that causes the vibration. The vibrator spinning constantly would create little vibration.
