IDEA:
-cap gets charged to full and is not currently connected to power supply
-it starts to discharge throught paralel LED + resistor over next 2 seconds
-when cap has too low voltage or capacitance to run an LED
transistors base reads LOW from LED and using a NOT gate, CAP gets connected to the
oower supply

TRICKY PART
i want the last step (battery charging the capacitor)
to be 0.2 seonds long no matter what, how could I do it?
WHAT I DO HAVE :
I have all basic elements for breadboard, timer NE555 chip, a RaspberryPI
Sidequestion:
When capacitor is empty and transistors base reads low at ONE POINT
is there any way I could make that point variable
ex. Transistor reading LOW when CAP is 1/2 charged or 3/4 ?
tyvm :))
