How To: The Hardware Hacker's Introduction to Microcontrollers, Part One: Anatomy of an Arduino

In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it mind-boggling! The world of microcontrollers is fascinating, engaging, and an awesome hobby; it never gets boring. I'll be focusing more on I/O and analog based microcontrollers, such as those running Arduino, and using Atmel chips as examples (these are most commonly available, and easy to program).

How To: Turn Off Amber Alerts on Your iPhone, Plus Emergency, Public Safety & Other Government Warnings

Amber, emergency, and public safety alerts on an iPhone are loud — startle-you-to-death loud even. They can happen at any time, day or night, and sometimes back to back when you're in a big city. Those blaring sirens can wake you from sleep, interrupt an important meeting, or disrupt an entire movie theater mid-movie, but you can turn most of them off if you're tired of hearing them.

How To: Your iPhone Can Detect & Alert You to Sounds Around You in iOS 14, Like Alarms, Knocking, Cats, Crying & More

For those that have deafness or are hard of hearing, the iPhone can be a powerful tool to communicate with others. It works with many hearing aids and Bluetooth headphones, Live Listen makes it easier to hear nearby people and sounds, and the Messages app makes it easy to chat with anyone. But iOS 14 takes it to a new level, one that even users with perfect hearing can benefit from.

How To: Share Your ETA to Contacts from Apple Maps Manually or Automatically

Are you here yet? When will you arrive? How long until you get here? How far are you? Hurry up! When you're meeting up with someone or a group of people, you may get flooded with messages like that. Instead of trying to answer them mid-trip, you can send them your status from Apple Maps, so they know precisely when you'll arrive, and they'll even get updates if traffic is holding you back.

How To: Lower Vibration Feedback on Your Pixel 2 to Make Notifications Quieter

Haptic feedback and vibration of our smartphones have come a long way in recent years. These features are much more premium now than they once were, but most users are still unable to adjust the intensity for notifications or phone calls. Most higher-end devices make less noise on surfaces than in the past, but adjusting these values can still come in handy even today.

News: The 8 Best FaceTime Features in iOS 12 for iPhone

From its introduction and all the way through iOS 11, FaceTime has been restricted to one-on-one calls. Apple will be changing that in a future iOS 12 update with Group FaceTime, which adds support for up to 32 people total in group audio and video calls. But that's not all we'll be getting in iOS 12 — there are more features that FaceTime has or will be getting soon that you should know about.

How To: Stop Incoming Calls from Taking Over Your iPhone's Entire Screen

Incoming phone calls and FaceTimes, whether you want to answer them or not, will take over your entire iPhone's screen — no matter what you're in the middle of doing on the device at the moment. You could be browsing the web, playing a game, or chatting on social media. It doesn't matter, you'll get interrupted. But you don't have to put up with it anymore.

How To: Use Business Chat on Your iPhone to Securely Interact with Companies via iMessage

Apple first announced Business Chat, a new way for customers to communicate with companies, at WWDC 2017. While Business Chat did not arrive with the initial release of iOS 11, Apple pushed it out in iOS 11.3 so companies can offer customer service in a whole new way, and it works pretty much the same in iOS 12 and higher as it did back then.

How To: Invite People to Messenger Group Chats with a Link So They Can Join Right Away or Wait on Approval

While some of our group chats should probably remain private and closed off, others will only get better with more people. Whether you're organizing an event and need a headcount or you want to share a funny YouTube video with a large crowd, you can add all the friends you wish to on Facebook Messenger by sending them a unique link.

How To: 3 Tips to Get to Inbox Zero Faster in Gmail

On average, an office worker receives 121 emails a day. Many of these emails are trivial and don't require immediate attention. While Gmail's automatic spam filters catch plenty of irrelevant emails, some still make their way into your inbox. Fortunately, Gmail's tools aren't limited to just spam filters.

Coinbase 101: Fees & Fine Print You Need to Know Before Trading Bitcoins & Other Cryptocurrencies

Coinbase is the primary go-to for many users when it comes to investing in Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Ripple (XRP), and more, due to its user-friendly interface. But before you join them, know that the ease of use comes with a price. Coinbase charges fees for each transaction, and your bank might even add charges on top of that. Plus, there is some fine print to be aware of.

How To: Secure Your Instagram Account by Adding 2-Factor Authentication & Managing Privacy Settings

The photo-centric Instagram app is a great way to share "evergreen" pictures and videos when compared to Snapchat and Facebook's new Messenger Day feature. But like all social media, keeping the account secure is an essential aspect, as it restricts unwanted viewers from seeing your content and can prevent unauthorized users from accessing your account. Instagram has several methods for locking down the account including a new two-factor authentication (2FA) mechanism.

How To: Message Effects Not Working in iOS 10? Here's How to Enable Them

As iOS 10 makes its worldwide debut, many users are noticing that the promised iMessage effects feature in Messages is not working properly. Instead of seeing the actual effects, messages will come through like normal, but with text describing the effect they were sent with. On top of that, you can't send your own message effects if you're one of the affected users.

How To: Make an SMS Intruder Alarm

This tutorial shows you how to create an intruder alarm that sends you text message alerts when motion is detected. This may sound complicated but I am pretty confident any beginner with electronics should be able to do this just fine. The range sensor senses motion and tells your Arduino board to send the text (SMS). So you can leave the intruder detector at home, connected to your network, and still receive the SMS alerts, no matter where you are, as long as you have cell phone service.
