Hello there...
Im currently building a pulse generator using 555 timer. The attached photo shows how its setup.
The frequency changes works just fine BUT the output voltage varies when i change the freqency. When set to low frequence (1-20Hz) i measure 5V peak to peak but when i turn up the frequency it gradually decrease the voltage and ends up with 4.4V at 2k Hz, even without load.
I guess thats not supposed to happen.
