I AM LOOKING FOR AN OSCILLATOR OR CIRCUIT THAT COULD MAKE A TAILORED PULSATING VOLTAGE OUTPUT. I have a circuit that uses voltage to get variable frequencies, but what I need is the reverse, I need an Oscillator or any circuit that can by means of a potentiometer or variable capacitor create a pulsating tailored voltage, quite the opposite of what can be seen in this video: https://www.youtube.com/watch?v=ShI8od3JAec
Dear HarryA and all relevant Electrical and Electronics Engineersin this forum, I have found a number of circuits that will give you HarryA and the relevant participants what I need. It is a pulsating voltaget that will make a LED or light buld fade in and fade out .One term used though not professional is: NE 555 | slow blink fade in fade out circuit (https://www.youtube.com/watch?v=Xyi6eaRnn9c ). I am clumsly posting the url for this video on youtube. A second example is the Turn signal running lights which lights some LEDs and keep one lit whcih will help me to achive the pulsating voltage by means of LDR's, yet this approach is not professional, it is better than an LDR on top of an LED that when turned off will drive the voltage to zero, something I do not want, I want a positive voltage sweeping from one to ten volts periodically and this second circuit can help ( https://www.youtube.com/watch?v=8e1S6ynWlqk )
