The voltage of a battery depends on how much charge it has.
So if your battery is rated 0.5 C it'll only be able to supply 1000mA (for 2 hours).Ħ0*21 would be well over 1000mA, actually 60*16 is just below 1mA, so this would fit your problem. It depends on the "C" or discharge rating of the battery. It's actually quite impressive that it works.Įach NeoPixel can draw up to 60 milliamps at full brightness.Ģ000mAh does not mean it can (always) deliver 2000mA. Since your voltage isn't stable, your amperage might not be as high and the resistance may be a little big. You could try powering the strip from the middle. A chip can get enough power to run, but not enough to work properly.Īdafruit has an extremely elaborated tutorial/userguide.
Hence, if your Arduino program works today, it'll work tomorrow.Īnalog devices, or electricity is (in my eyes) often a bit vague. When something works, but not completely, it's often due to power issues.Įmbedded things, microcontrollers/Arduino are fairly robust and "logical".
