Battery Power for LED Pixels and Strips

LED strips aren''t picky about which side they receive power from, only data. In a pinch, if the situation really calls for it, you can connect the battery pack (with diode, if used) to the OUT end of the strip, then power the Arduino from the + and – connections on the IN end (along with the serial data and clock signals). This isn''t

A better power supply for microcontroller circuits

One potential addition source for glitches caused by the power supply, would be if the power transformer''s output voltage is too close to the necessary input voltage of the linear regulator. For example the 7805 linear regulator requires an input voltage of 2 volts higher than the output (i.e. 7V input), and I like to add 1V as a margin of tolerance to make it more reliable. Adding the
