Question on heart_pulse_blood_flowing.ino example about fastled_examples HOT 2 CLOSED

Hello @francoisoudot <https://github.com/francoisoudot> Honestly I'm not actually sure where the 5 comes from in the 5/NUM_LEDS/2 part. Chris Thodey's original setup had 78 pixels and he might have determined that a multiplier of 5 gave the "correct look" when taking into consideration the average time for a heartbeat QRS interval (or maybe it was the heartbeat QT interval?). With his 78 pixels that first part would give around 5/78/2 = .128 With my 32 pixel example that first part would give 5/32/2 = .3125 Of course if you only had 2 pixels or 200 pixels it would be very different (giving 5 and .05 respectively). If you aren't getting a nice "heartbeat" look, maybe try changing that multiplier a tiny bit? Also try setting your NUM_LEDS to 32 to see the heartbeat look I'm getting if you didn't try that yet. Here's the original G+ thread (which also has Mark's thoughts and Chris's code) which I based mine on. https://plus.google.com/+ChrisThodey/posts/UdyqYt318gF Let me know what you discover and I would be curious to know how may pixels you have in your setup. And of course feel free to make a new FastLED G+ post too showing off what you're working on or if you want more people to see your question. (If you post in that old G+ thread only those that originally commented would be likely to see it, so probably best to start a new one.)
