Topic: problem in accessing values from python correctly (Read 259 times) previous topic - next topic


hello ,
my goal is to take a specific value as an input from the user (using python) and by using serial communication , i want this value to be read by the arduino uno and be applied on a motor as its speed .
but i am facing a problem in reading this value by the arduino , i guess it is not reading it as i want from the python.
so what is happening? and what i should do to take this value as it is from the python?
Code: [Select]

void loop()
 if (Serial.available()>0)
  speed = Serial.read()
  if (speed >= 0 && speed <= 255)
