This demonstrates how to wire a 555 timer chip for Pulse Width Modulation. Items used: solderless breadboard, 555 chip, 510 ohm resistor, 100k ohm variable resistor, 1 RGB LED at 20-25ma, wires, and 9v battery. And those vertical lines are what i mean in terms of what you can see only on the camera. You can see the led light of course without the camera.
A basic instruction for electronic enthusiasts. I use an RGB LED and a 510 ohm resistor as I may change from 6 to 9 volts later, but with my LEDs i could go as low as 330 ohms. I sacrifice some brightness for the sake of longer life. To choose your resistor, the value in ohms = voltage of your batteries or power supply / (as in divided by) the amperage that your LED needs to run.

Apple seeded software testers iOS 14.5 public beta 6 today, Wednesday, March 31. The update includes a new battery calibration for iPhone 11, 11 Pro, and 11 Pro Max, as well as two new Siri voices.
Whether you have or are getting an iPhone 12, 12 mini, 12 Pro, or 12 Pro Max, the default way to check the current battery life is via the tiny battery icon in the top right of the status bar. But that does not accurately depict how much juice is left, not as a specific percentage indicator would. If you want the exact number, there are some not-so-obvious ways to find it.
Out of all the myths about the iPhone's battery, one that's very true is that charging your phone overnight is bad news. Keeping the charge level at 100% puts the battery under strain, which can permanently damage it. Apple took steps to address the issue in iOS 13, where your battery stops charging when it hits 80% in some scenarios, but that's not always enough.
With Android 10 "Q" right around the corner, now would be a great time to get accustomed to the new system-wide dark mode it's bringing with it. Dark themes not only allow for more comfortable viewing at night, but can also consume less battery at the same time. With a single button tap, you'll be able to enable this new dark theme for all compatible apps without having to jump through hoops.
As the premiere app for chatting and video calls, it only makes sense for Skype to provide a dark theme to help prevent eye strain and minimize battery drain. Not only that, it has to also keep pace with popular messaging apps like Facebook Messenger that also have the feature built-in.
For the first time since its inception, the famously hidden System UI Tuner has to be unlocked in a new way. No longer can you long-press the gear icon (found in Quick Settings) until it spins and reveals the hidden settings option. With Android 9.0 Pie, there's a new workaround to reveal the menu.
