Hi.
I am trying to create a mini signal generator using 555 timer IC.
I created the circuit using
C1 = 10e-6
R1 = 1000 Ω
R2 = 5400 ~ 55400 Ω ( I varied the R2 by adding a series of 2200Ω, 2200Ω, 1000Ω resistors and one 50000Ω potentiometer
From what I know the output voltage of the system should yield 2/3 the Vcc.
Since I am using 9V battery, it should yield ~ 6 volts. However, I am only getting around 4V. Please let me know what I can do to maximize the output voltage.
Thanks in advance!
PS. also I know that input voltage is 4.5 V ~ 15V for IC timer. What would happen if I input 2 9V batteries and provide 18V in series?
