Hello, Good Morning ...
Looking at the circuit ( Comparator Oscillator ), tried
to implement a Battery Monitor ( 9 VDC ), Lower two levels,
The problem is that I can not properly adjust the values of oscillation between these two levels
( now Oscillating between 6.45 VDC and 5.45 VDC ) .-
At the lowest Level regulator 7805 no longer provides 5.00 VDC.-
As I 5 VDC need to ensure that the Oscilating levels were
6.35 VDC and 7.35 VDC.-
Could you tell me Equations Calculation and Considerations
this circuit for R1, R2, R3, R4, R6, R6 and C4.-
Thx.-
Antonio.-
