And of course there are flashing LEDs. An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and ...

Keeping track of all your electronics, how they consume power, and whether they're on, is tough business. If you want to really monitor what's going on, the Powerduino is a programmable power ...

This port is primarily used for connecting the board to the computer for tasks such as monitoring serial data received or produced by the Arduino. However, the USB port doubles as a power port.

The Arduino 101 equipped with Intel's Curie module integrates a 6-axis gyro/accelerometer and Bluetooth, which sets it apart from the rest of the Arduino line up. What the heck is an Arduino?

STMicroelectronics has introduced a precision digital current, voltage and power monitor with a an I3C bus interface. Called TSC1641, it has two 16bit ΣΔ converters at its inputs, allowing ...
