Building an affordable lower power linear actuator using little Arduino hardware and programming. James Bruton takes you through the process ...

The Arduino IDE is used to write the program that will interact with your Arduino and the devices connected to it. In the Arduino world, such a program is called a sketch, which has its origin in its ...

With the connections in place, [Ilias] was able to communicate with the Nokia phone using a program called Gnokii — a utility written specifically for controlling the phone with a computer.

The electronics is where this project really shines, with an Arduino controlling the mode of fire (auto, semi-auto, and a 3-round burst), and the number of rounds per second adjustable with a pot.

By controlling analog circuits digitally, system costs and power consumption can be drastically reduced. Arduino already include on-chip PWM controllers, making this effectuation easy. In short, PWM ...
