While building robotics projects, the importance of controllers and motors cannot be overstated. These components are the heart and soul of any robotic system, providing the necessary control and ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Despite their similar sizes and affordable prices, microcontrollers and single-board computers have vastly different specifications and use cases. After all, MCUs are designed for circuitry, ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires ...
