I've played a bit with Arduino and 433MHz transmitters a few years ago : I just recorded the signal that open the portal of my residence then played it back and successfully opened portal... yaaay \o/, I also played with motors thanks to shields etc.
But right now I have a new project involving programmable and adressable LED Strips. I've searched the internet about what I can buy and it seems the majority of LED strips (on Adafruit at least) work at 5V.
Arduino takes 5V as an input too IIRC.
So my question is :
Is it possible to power an Arduino and a LED strip (approximately 50cm or 1meter), with a 3.7V LiPo battery ?
Can the Arduino output a regulated 5V, from the 3.7V provided by the battery ?
(I think I'll go one of the tiniest versions, or even just use an Arduino to program an ATtiny/ATMega - I don't know which one would be good to control LED Strips - stuck on a breadboard. If you have any advice about it, I'll take it too)
If no, what could I do which would be cheap and tiny, to up the battery voltage to 5V so it can power the Arduino & the LED strip ? Or.... should I instead buy regular 1.5 Volt (1.2V for NiCd) rechargeable batteries and use 4 of them in series to get roughly 5V ?
Thanks for your help
