[ad_1]
i made a circuit that management motor velocity and point out the motor velocity ranges with leds, the push button management the velocity degree and leds

now i wish to make battery low voltage indicator so the battery led blinking in crimson when the battery decrease than 680
and this battery led flip on and off with the degrees leds so if
motor and leds are working = the battery led blinking
motor and leds cease = the leds stops
i attempted this code however it not working in any respect simply blinking the battery led and no motor management
