Hello . I want to ask how can I control high voltages with arduino. And which High voltage motors work with arduino? And last question . What is High voltage with arduino?
Define "high voltages". AC or DC? Put numbers on it.
The absolute maximum DC voltage that can be applied to an I/O pin or power pins 5.5V for a 5V Arduino. Consult the data sheet for others.
To control high voltages use a mechanical relay, solid state relay, MOSFET, or other solid state switching device for the voltage (DC or AC) and current to be controlled.
Motors can't be directly controlled by any Arduino. If you can find a driver, for the motor, that can be controlled by an Arduino then there you go.
I wonder how are big CNC machines controlled . And they use 380V AC.
A post was merged into an existing topic: Question about Arduino Mega 2560
An Arduino can be used to control the motors on a CNC machine through appropriate motor drivers, for example stepper or servo drivers. These take logic levels from the Arduino at 3.3 or 5v and are supplied with an appropriate high voltage, that could range from say 24v to 80v or in some cases an AC mains supply. "grbl" is an Arduino library that can drive simple CNC machines.
"Big" CNC machines are unlikely to use an Arduino as they have much more sophisticated requirements. They might use an Intel main processor and DSP processing to generate signals for the motors.
Where can I learn more about them?
About what exactly? Try Google.
I found some tutorials online.
