When the power goes out at night, a computer loses its date, so you have to put it in again in the morning. What's wrong, and how can it be fixed?
In tinkercad it is requested to use a system that reads an IR keyboard, and if it is pressed: button 1 turns on a spotlight and sends the message to an LCD: Garage spotlight on button 2 turns off the light and sends a message to an LCD: garage light off button 3 activates an ultrasonic sensor and if it detects something less than 1 meter away, it activates a buzzer and a message on the LCD: intruder detected. And if the alarm is activated it can only be stopped with the red on button of the IR keyboard
