I tried to make a Python script that sends a message to my arduino uno r4 when I click my mouse the arduino should power pin 11 when the mouse is clicked and unpower pin 11 when the mouse gets released. I just can’t get it to work. If there’s a better solution or you know how to help feel free to help.

i used a script from a tutorial i found:
phyton:
.

.

.

import serial

import time

serialcomm = serial.Serial(‘COM7’, 9600)

serialcomm.timeout = 1

while True:

i = input("Enter Input: ").strip()

if i == "Done":

    print('finished')

    break

serialcomm.write(i.encode())

time.sleep(0.5)

print(serialcomm.readline().decode('ascii'))

serialcomm.close()

.

.

.

Arduino:

“String incomingByte ;

void setup() {

Serial.begin(9600);

pinMode(LED_BUILTIN, OUTPUT);

}
void loop() {

if (Serial.available() > 0) {

incomingByte = Serial.readStringUntil(‘\n’);

if (incomingByte == "on") {

  digitalWrite(11, HIGH);

  Serial.write("Led on");

}

else if (incomingByte == "off") {

  digitalWrite(11, LOW);

  Serial.write("Led off");

}

else{

 Serial.write("invald input");

}

}

}
