These examples show Prometeo's working style before subscribing: not abstract promises, but published practical cases.

Analog components
Simple voltage divider
A classic example showing how Prometeo connects theory, calculation, SPICE simulation and measurable results.

Digital components
4-bit up counter with LEDs
Sequential logic, clock signals, reset and LED outputs in a schematic designed for human reading.

Arduino UNO
Ultrasonic distance alarm with Arduino UNO
A useful prototype with an ultrasonic sensor, local alerts and validated code for building something tangible.

Raspberry Pi
Air quality alarm with Raspberry Pi 4
Sensors, touchscreen and clear alerts that turn environmental readings into a practical tool.

UGV robot
UGV obstacle stop with Raspberry Pi
A robot that stops before obstacles: practical for learning control, safety and repeatable testing.

FPGA
Voice-controlled RUN/STOP on ULX3S ECP5
A validatable device case with FPGA toolchain checks, clear editorial structure and validation evidence.
What you can check in each case
When one case saves you an afternoon of doubt, full access already pays off.
Prometeo is made for learning by building: less scattered searching, more guided practice and more confidence in the lab.
