This effect is also known as the breathing LED or the Apple LED. 8212019 In this post we will learn how to assemble an IC 555 astable circuit for generating interesting LED flasher circuits with blinking and fading light effects with some minor modification and enhancements. It became very popular and i received many comments and emails with people that made this circuit and worked fine as well as comments with people that had troubles converting it to operate at 12 volts supply. On the SunFounder Uno board pin 3 5 6 9 10 and 11 are the pins of PWM with marked. Any higher than 1K and the LED will be dim. You can connect any of these pins.
555 LED Pulsing Breathing Circuit Here is a circuit for simulating breathing pulsing LED with the 555 timer chip.
That brings the total to 450 uA which makes your idea just about feasible. In other words the brightness seems to be bouncing back from 0 rather than slowly gliding back up. Also dont go for a bargain-quality battery. I followed the Fade tutorial on the Arduino site which gives me what I want but I notice that the change in brightness is much more noticeable when the intensity is at 0. Any higher than 1K and the LED will be dim. The astable multivibrator mode is the most fundamental mode of operation of the IC 555.
