This is my 4x4x4 led cube project, done with MSP430, using only 3 pins of MSP, the circuit diagram is shown in the photos, the hardware consists of 3 shift registers, 74595, and 4 NPN transistors...





 
you can learn how to make a 4x4x4 LED cube by instructables or youtube or some other sites, its easy to make...
but make sure that you make exact same connections as shown in the cicuit diagrams... or else this code won't work in the new hardware...



the hardware can be built as shown in the circuit diagram...

the code is given below, you can changes it and make your own animation with it....

This is a heart beat counter, which displays the result on an LCD, it amplifies the signal by a dual op amp IC, and passes it to msp, as an interupt to count the number of pulse for 15 secs, it uses internal clock, so its not so accurate, but it will give you a good precised result...
i have given all the neccassary information, including the schematic, the video link, and the code, with the header file..
here is its video...

This is an 8x8x8 LED cube, designed by me, i think its the most compact circuit i have ever seen on the internet regarding a cube of this size...

When you click on the images - it opens them up in their original size.  Nice looking project BTW!

Nice work!  Love the simple yet practical use of perfboard in your projects too

hi friends, this is my project on Digital clock, using MSP430G2452 [u can use any 20 pin MSP controller], i have uploaded its schematic with the code here, you can see it working at...

the ir pair should be 1 led and 1 ir sensor (photo diode? still a diode?)
 
the vishay tcrt5000 is convenient to use as it comes in a single package and aligned already. it can be have in ebay for a few dollars (multiple units).
 
i used that for proximity detection but it could also be used here for pulse sensing with op-amps.

did u try just use the 3.6v from launchpad? the lm324/358 should work w/ 3v. any reason u need 5v?

I assume 2 IR LEDs then for the pulse monitoring? 1 for shinning into your finger, another for picking up the change in the received LED brightness which the variations can be observed as beats? Something like that?
 
Very sweet project, thanks for sharing!

That is awesome!

Maybe you should run around a little and sample your HR again  :thumbup: . Nice project!
