I am having a problem communicating with an LED. (Never thought I'd hear myself
say that!)
I have code in LC in a slider:
-- We are open driver ... for text update
on mouseUp
put the thumbPosition of me into tValue
doUpdate(tValue)
end mouseUp
on doUpdate tValue
put gThePort into thePort -- global port "/dev/cu.usbmodem1a21"
read from file thePort until empty -- clear the buffer
put it into field "Data" -- just to see what garbage is left over - not
needed
wait 30
write tValue to file thePort -- Vaule is 0 -255 as per the Analog specs of
a PWM on the Arduino Uno for an LED
read from file thePort until empty -- Arduino is set to send back the data
received this is so I can see it
put it after field "Data"
if the result is not empty then put the result into field "Results" --
gives us our eof
end doUpdate
I send out a 125 but I get back three lines:
1
2
5
but the analogWrite is looking for 125
void loop() {
// check if data has been sent from the computer:
if (Serial.available()) {
// read the most recent byte (which will be from 0 to 255):
char received = Serial.read();
// set the brightness of the LED:
analogWrite(ledPin, received);
Serial.println(received);
}
}
If I change the Serial.println to Serial.println(received, BYTE); I still get:
1
2
5
But if I change it to Serial.println(received, DEC); I get these results:
49
50
53
So How do I send a number as a number and not as single digits?
