If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty ...

but for the purposes of measuring battery power in a system or deciding when to send a “low battery” signal, it’s an attractive solution. Being an Arduino library, CPUVolt makes this idea ...

If you’ve messed with Arduino, the inexpensive micro controller, you’ll know that you can run a small motor or turn an LED on and off, but anything else – powering a pump, turning on a light ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

one that fires off an SMS to predefined contacts upon mains power failure. The first step was to enable communication between an Arduino Micro and a Nokia cell phone. His Nokia 3310 uses FBus ...

Original Circuit Diagram: Arduino UNO R3 Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

Thus, for Arduino, you merely need a battery pack that keeps the voltage above a certain level, along with a primary shield to manage the power. Even if the power drops on the Arduino, you won’t ...

By using an EEPROM chip instead of an SD card, we save space, power, and complexity. Luckily, connecting the EEPROM module to an Arduino board is simple. Note that the address pins need consideration ...

We now have a working traffic light simulator: Once you've uploaded the Sketch to your Arduino, if you plug in an external power supply to your Arduino's DC barrel jack, and unplug its USB cable ...
