So I built a 555 astable oscillator. I wanted to get 50 KHz on my output, which I have achieved, but the values of my components do not match the formula I have calculated. I have: R1 = 98 ohms R2 = 67 ohms Cap = 100nF So I have: 1.44/(98 + 2 67) 100nF Which should be 62KHz. Also can anyone explain why im getting 1volt on output with 5 volts in. Thanks in advance for any help.
