so I built her a "Button Box" based around an Arduino. Open source ... For a battery, I just used a module I had laying around. So, uh, she's got about 13.5Ah at 3.7V worth of battery in her ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

This year at CES, Intel introduced Curie — a button-sized system-on-chip ... that the first product to use the Curie module is a brand new, low-cost Arduino board called Arduino 101.

a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project. You'll need a prepaid SIM card, an Arduino, a GPRS shield, and a few other odds and ends. Luckily ...

Makers, developers and hobbyists that enjoy tinkering with Arduino wearable open ... with an optical sensor to detect button presses. “The Tog base module contains a densely packed PCB assembly ...

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386. A single button on the Arduino helps cycle ...

The button-sized Curie is ... ARM Cortex microcontroller. Called a module, it needs a carrier board to interface with this hardware. This is where the Arduino/Genuino 101 comes in.
