You will have to forgive me, for asking but the last circuit I built was with vacuum tubes, and the computer was not yet invented. My great nephew asked me for help building his RC FPV station. I have flown rc for many years but things have changed greatly in the electronics world. What I need is a schematic to follow to build this simple circuit.
Items on hand: One 8mm Led bi color red green, one 555 timer, 2n3904-g05 transistor, 10v zanier diode, 103 10nf capacitor, 22uf capacitor, 560ohm resistor, 10k resistor, 1k resistor, n40 diode, 56k resistor, 340 resistor pizo.
Desired effect:
I thank you very much.

Desired effect:
- When the voltage is 12.60 – 11v green light side of the led turns on
- When voltage is 10.99 – 10v the green side of the led turns of and the red light is flashing on once every 15 seconds
- When voltage is 9.99v-9.5v the light flashes one second on one second off
- When voltage is 9.49- 6v goes constant red
- When the voltage is 9.99v the alarm chirps once every 15 seconds
- 9.5v- 9.25 the is alarm that sounds on every 2 seconds
- When the voltage is 9.24v-6v the alarm sounds constant
I thank you very much.
