Does the port to comunicate from Python->to Arduino has to be the port that arduino uses by default or can it be any port? I mean, if arduino uses COM3 do I have necessarily to use COM3 on ”ser = serial.Serial(’COM3’, 9600, timeout=0)”. I want to make a both

Hi Tasya, You are probably running into a common issue we all have to deal with: opening up the serial port on the computer side of things causes the Arduino to reset and wait in the Arduino bootloader for a bit. To guard against this, you’ll see computer-side code

You shouldn’t be closing the serial port in Python between writing and reading. There is a chance that the port is still closed when the Arduino responds, in which case the data will be lost. while running: # Serial write section setTempCar1 = 63

I have to unplug the board then. The same behavior is observed the other way round. If I send to my board over serial port (in my case USB) and don’t flush the input buffer, the LED is flushing up continuously and I get a timeout. The following code works:

According to the Arduino reference Serial.write() writes binary data to the serial port. Serial.print() prints data to the serial port as human-readable ASCII text. This sounds fairly straight forward but there is more to it that that and isn’t all data binary anyway.

Simply look in the bottom right corner of your Arduino IDE, and you will see some text containing the COM Port number. We will use this to initiate our Python serial connection, like so: arduino = serial.Serial(‘COM1’, 115200, timeout=.1)
