If you need a seven-segment display for a project, you could just grab some LED units off the shelf. Or you could build something big and electromechanical out of Lego. That’s precisely what ...

Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

This allows the implementation of any logic to handle the actual servo control. For example, you can make use of the standard Servo library for simple setups or add logic to control servos via PWM ...

This paper uses a simple two-wheel self-balancing car as the design platform., the gesture sensing system with MPU6050 serves as the main sensor. The data of two sensors are filtered and fused by ...

The design consists of on an analog design for a high voltage (HV) module, a very minimalist analog signal processing configuration, followed up by Arduino DAQ instrumentation. While there are many ...
