I want to control my arduino in real time with my pc.
For example, if I press the ''backspace'', my arduino will do something.
Is it possible? How ?
Is it possible?
Yes you use serial communication. Your PC sends the data to the COM port that is the Arduino and the Arduino reads the serial port and responds to what is sent. Look inside the examples in the Arduino IDE for how to code this.
Use a terminal emulator like PuTTY or hyperterm
