Go Speed Racer...Arduino Speed Test. We often teach beginning learners that the standard 16 MHz Arduino Uno is fast... really fast. 16 MHz means 16 Million cycles per second -- or that translates to 1/16 millionths of a second per cycle. That's a mere 62.5 ns. That's fast. So, is the Arduino _really_ that fast? Let's see...

A large chunk of Internet-of-Things projects revolve around home automation-- a classic example of which is automatically switching your lights on and off. Using the Blynk Timer widget , you can trigger specific outputs to fire at any time of the day -- even if your app is closed and your smart device is off!
Remote Power. During rehearsals, the prop was initially powered by a 12V wall adapter. It was bulky and not ideal for quick set changes between pieces.
This tutorial serves as a quick primer on flex sensor's, and demonstrates how to hook them up and use them. Aside from the sensor, the following materials are recommended: Arduino Uno -- We'll be using the Arduino's analog-to-digital converter to read in the variable resistance of the sensor.

Esta guía contiene toda la información que necesita para explorar los 21 circuitos del SparkFun Inventor's Kit para la placa Arduino 101. Esta guía se basa en la siguiente filosofía: todo el mundo puede (y debe) probar componentes electrónicos de vanguardia.
We've provided a library for the SparkFun Lightning Detector that configures every available setting the IC offers. Some of the features include modifying the sensitivity of the antenna, whether you're inside or outside, fine tuning when the IC triggers an interrupt, or modifying the resonance frequency of the antenna.
