Please I need a expert help here or any experience hobbyist. I built this circuit and connected the output to LED to blink. Unfortunately, the LED did not blink but only on, so I begin to change the value of C1 & R4 to see the LED blink. At a particular value of C1 & R4, I coupled a capacitor to the LED from the output the LED blinks but was very faint. I coupled the capacitor since it passes time-varying signal and I also don't have an oscillator. What am asking now is that, is the circuit oscillating very fast that is not feasible to the eye?
