This project simulates a 2D LiDAR system using SR04 ultrasonic sensors mounted on a stepper motor. The system is controlled by an Arduino UNO (Elegoo R3) and scans the surroundings, sending distance ...

It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at low speeds. Commonly found in CNC machines, 3D printers, and robotics, they ...

[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...
