Hey everyone, I have been having a problem trying to send commands to the UNO from my terminal, I have been using the commands:
echo -e "\x00\c" > /dev/tty.DEVICENAME
To turn off the light and
echo -e "\xff\c" > /dev/tty.DEVICENAME
To turn the light on, and this works, just like a python script I’ve written, with one major flaw: it will only work if the serial monitor from Arduino is open.
I have tried using the stty -f command, and many other things, however nothing works for me.
stty -a < /dev/tty.DEVICENAME when the Serial Monitor is open, it gives me

Any help would be appreciated!
The code I am using is the default “dimmer” tutorial, however instead of using the programs it suggests I have been sending bytes from the terminal or python scripts
