Hi everyone,
Recently I was assigned my first term project on voltage indicator via LEDs. I have uploaded the photos of the instruction and also the first draft of my plan below. The only part I am not so sure of is how I am using the comparator in association with the zener diode. The comparator will be used to decide the voltage level in which the supply voltage will start sourcing. Two comparators will be used since one is connected to 555 timer IC (for blinking mechanism mode 2 when voltage level is between 9V and 11V) and the other is going straight into the LED connection (for ON condition when voltage level exceed 11V). To keep this short, I am looking for some idea to modify the circuit to make it works efficiently and correctly. I would really appreciate any suggestion and comment from you guys.
Thank you very much!
