The Arduino Wire library is a core aspect of Arduino's integrated development environment, or IDE, and is a must-have if you're using sensors or extra microcontrollers in your project.

Step 6: Load the code onto the ESP or Arduino and follow the circuit diagram to build the circuit. Step 7: Make sure the servo is in the right orientation by powering on the ESP or Arduino and ...

Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.

Well tech tinkerer Joe Desbonnet has whipped up what he dubs "poor man's NFC" using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them).
