Hello, I am new to every circuit and the community. I could use some help. Could someone show me how to adjust the transistors and diodes in my simulation to match the ones in this schematic? http://pcbheaven.com/circuitpages/555_Breathing_Pulsing_LED/
This is a circuit that will create an adjustable triangle wave voltage source to drive an led, capable of simulating a "breathing" pattern. The two pots adjust the up and down ramp speed of the wave voltage. I have built it on a physical breadboard with success.
I will also need to figure out how to reverse mirror the led with another led so I can instead use two optocouplers working opposite each other to simulate both sides of the wiper in a pot. I hope that makes sense. My end goal is to use this circuit and optocouplers (led and photoresistor combined) to modulate the resistance of external circuits such as guitar effect pedals and circuit bent kids toys. I hope this makes sense. Any help would be greatly appreciated.
