As for having the flicker come back after adding more lights, it is most certainly true (capacitors have a finite capacity), but you have said the lights keep glowing after you switch off the display, this indicates you are using a massive capacitor and this issue will not appear unless you connect much more, and once it does you can use a full wave rectifier to keep it at bay without needing to increase the … The most popular Arduino is the Arduino Uno. After a bunch of head scratching, we also figured a portion of the lights must work on the negative cycle of the AC. Some Christmas light testers work by sliding each Christmas light bulb through a hole.. As a bonus this circuit offer the option of dimmer light level (reduced current) resulting in even more longevity. Any device built and connected to household power has the capability of causing injury, electrocution, fire, and damage to other equipment and property, and even experts in the field are not immune to mishaps. Since warm white is essentially a color that attempts to imitate an incandescent bulb, be aware that every manufacturer's version is different. Place this bulb in the first section of the string of lights. Find a package that has at least one bulb with a red mark on the end. Looking at the loaded output waveform on a scope, you certainly see the ripple voltage. But even the minimum DC level on the waveform is far from the point where you'd cause the LEDs to go out, or even dim significantly. The circuit shown here presents a reasonably filtered DC source, and can be adjusted to accommodate a lot of light sets and brightness levels (I've used mine to power 8 100 LED sets so far). We, as humans, are very ignorant. So that's all there is too it. Keep the cords dry, and make sure to use surge protectors to minimize damage in case of voltage fluctuation.
