|LED Flasher using PIC12F509 or PIC12F1840 and GC Basic.
Ornamental LED flasher - pulser- twinkling star.
Can use 2x NiMH or 1x LiFEPO4 battery.
Solar input keeps the battery charged and turns off the display during the day.
LEDs can have greater forward voltage than the battery supply but can be driven by utilising stored energy
in an inductor.
LED brightness can can controlled by pulse width.
