After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

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 ...

Open-source digital twin for a line-follower robot, integrating MATLAB controller, Unity 3D virtual model, and ESP32 physical robot. Features PID control, UDP/TCP sync, and HTTP dashboard. For ...
