Hi.
I am doing a project using 555 IC and potentiometer/variable resistor, creating pulse to control a propeller spinning speed.
I wanted to add in a 6 LED, 3 Green/2 Yellow/1 Red, which will be control by the same potentiometer/variable resistor that able to indicate the spinning speed of the propeller.
Example: in green and yellow zone, the spinning speed is safe. But when it reaches red zone, it will mean that is spinning too fast and need to slow down.
This is my idea:
but instead of using the Arduino card, i need use other components, ICs, etc.
The attached file I had uploaded is the circuit that controls the spinning speed of the propeller. So, I need to combine the circuit diagram in the photo and also the LED circuit together into one circuit diagram.
Hope you guys can share some tips and ideas, Thank You.
