Hi,
I am using two 555 to create a sweep oscillator.The range of voltage on control voltage pin of IC2 swings from 4.6 to 8.6 volts.How do I increase the range using additional transistor from 1 to 11 volts?If not then as much as lower than 4.6 and higher than 8.6 volts.I want an aotomatic operation so I cannot use a pot.
