I am currently working on a project with Arduino that involves communication with Python. After researching online, I found a sample code for Arduino Python serial communication which lights up an LED when the number 1 is entered. Although both the Python and Arduino codes are functioning properly, the LED is not lighting up as expected. I have confirmed that the board is in good working condition by testing other basic examples.
Arduino code:
I
void setup()
{
pinMode(12,OUTPUT);
digitalWrite(12,LOW);
Serial.begin(9600);
}
void loop()
{
if(Serial.available() > 0)
{
if(Serial.read() == 1)
{
digitalWrite(12,HIGH);
delay(2000);
}
}
else
{
digitalWrite(12,LOW);
}
}
Python Code:
import serial
import time # Required to use delay functions
arduinoSerialData = serial.Serial('/dev/ttyACM0', 9600) # Create Serial port object called arduinoSerialData
time.sleep(2) # wait for 2 secounds for the communication to get established
print ("Enter 1 to turn ON LED and 0 to turn OFF LED")
while 1: # Do this forever
var =input() # get input from user
var=var.encode()
arduinoSerialData.write(var)
