What am I doing wrong or misunderstanding? Thank you. #However the same thing does not work with numbers. #Note: for characters such as 'a' I set data = b'a' to convert the data in bytes Print("Connection to " port " established succesfully!\n") Here is the code I use in Python: import serial I am missing something but I cannot find what. However, when I input a value into the Serial port or through Python, for instance 0, it gives me 48 as answer (which, interestingly, is the ASCII code for 0!) and lights up the LED which is not what should happen since at 0 the LED should be off!! NOTE: I am using ARDUINO UNO and PYTHON 3 Here is the Arduino code, ideally it should get a value from the usb port through python or the serial monitor and then adjust the brightness of the LED according to the value. However if I send a number it looks like it simply does not get it. I can easily send characters such as 'm', 'o' and so on. Once I set up a basic arduino-LED connection, I have problems sending INTEGERS to arduino through the serial port. By first sending them to the Arduino, which will in turn send it back to the computer that Python then prints out.I am new to Arduino (and computer programming in general), so I apologize if this question looks silly. Once you run the program it will print out the majority of ASCII characters. You can also change the baud rate in line 3 of the Python program and line 2 of the Arduino program as long as they stay the same. Whatever that is should be what is in quotes in line 3 of the Python program. To determine what serial port your Arduino is connected to look at the bottom right corner of your Arduino sketch. Sleep(.1) # Delay for one tenth of a second Print ser.readline() # Read the newest output from the Arduino Ser.write(str(chr(counter))) # Convert the decimal number to ASCII then send it to the Arduino Ser = serial.Serial('/dev/tty.usbmodem1d11', 9600) # Establish the connection on a specific portĬounter = 32 # Below 32 everything in ASCII is gibberish After a few seconds, the uploaded program will run, and you’ll see an LED light blink once every second: After the upload is finished, the USB cable will continue to power the Arduino board. During the upload, you’ll see LEDs flashing on the board. Next in Idle create a new window and create the below program. The USB cable provides a serial connection to both upload the program and power the Arduino board.
