Thanks again,
BTW, the 555 timer is it important to be build?
Because I am interested to control the servo angle using microcontroller PIC16f818.
pic 16f818 contain internal timer. So, I think no need of Timer 555?
Just asking?
BTW, the concept of 20ms? and the range 1ms-2ms with 1.5ms to be 90degree.
The on signal for 1ms-2ms (The on signal to control the angle) and off signal for 10-30ms (Just to make sure the signal servo is on).
Is this how it is?
Thanks in advance
