In watchOS 10, Apple decided to bring back widgets in a big way, making them a crucial part of the Watch experience with a new feature called the Smart Stack.

Smart watches can be a great tool to help you reach your health or fitness goals. Constant reminders can be a demotivator too. Here's a few tips to make your smart watch work for you.

Sensors in the smart watch can recognize simple gestures from the hand that wears it. The research team turned to 10 volunteers to test the accuracy of its system.

Unlike a normal Arduino program, all the work in a typical Watchy program happens in setup() so the watch can mostly sleep and it updates the 200×200 typically just once a minute.

You can use automated replies to respond to text messages on your Apple Watch and even add your own replies to the list.

Specifically, this project details how to make a smart watch that displays time, date, incoming calls and texts from a Nokia 1100 cell phone display and a few other bits.
