Hello. I'm using a laptop and I'm wondering if it's possible to send keyboard input to an Arduino Uno through the usb serial port without a delay. Any suggestions?
There will always be a delay, it's unavoidable with serial comms.
What would be an acceptable delay?
You can check out other serial monitor like programs, this was recommended in another topic:
I don't know if it sends to the COM port as you press keys, of it if waits until you press enter like the IDE's serial monitor.
