Hello, can you please help me with the following question?
I need to design a circuit to measure battery voltage using LED's.
V_in=V_max= 12v , V_min=8v
When V_in ≥ 9v LED1 will light up
When V_in ≥ 10v LED2 will light up
When V_in ≥ 11v LED3 will light up
When V_in < 9v RED_LED will light up
you can use a one channel power supply (positive), transformer, resistors, capacitors, op-amps etc.
