Code to know the address “MAC” of “Monitor Series”: Code from which a module “ESP32” transfers data to another module and simultaneously receives data from the same module: Modul 1: Modul 2:
Third part of the project, communication between ESP32 modules.
The code of the three modules is: Module ESP32 Motion sensor, relay and lamp: Module ESP32 temperature sensor and LED: Module ESP32 receiver and web server for displaying the result:
Autostart Raspberry pi con LXDE-pi
Se puede abrir una ventana cuando arranca la Raspberry pi, debes escribir la siguiente linea en el archivo /LXDE-pi/autostart : @/usr/bin/python3.7 home/pi/Desktop/Neu3.py De esta manera se ejecutara el codigo del archivo Neu3.py cuando se encienda la Raspberry pi y se podra ver la ventana. Todo esto sucede porque uno de los archivos que se ejecuta […]
Calculation of a capacitor for an electric motor.
We can connect an electric motor to a single-phase power line, therefore, it is possible to operate an electric motor from a single-phase plug using a capacitor. What capacity should the capacitor have? and how should the capacitor be connected to the motor coils? These are two questions we will address on this page. We […]
Electron current and conventional electric current.
The electric current in an electric circuit is symbolized by the direction of the electrons through the circuit. The electrons flow at a speed of 0.001m / s (depending the wire and insolation composition), while the electromagnetic waves propagate at a speed of 300.000 Km/s, from the voltage source to the electric resistance, and after, […]

Electric motor three phase, nameplate.
Electric motor nameplate Where we can define: Hz (Hertz). Hertz is used to measure frequency of cycles per second. KW (kilowatts). We use kilowatts to know the power. A (Amperage). Amperage indicates ampere consumption. Rpm (revolutions per minute). Speed at which the shaft rotates. V (Voltage). Working voltage which can be 230V or 420V. […]
