Hello, I have several questions about the UART
How does the UART sends information from the computer to the Microcontroller? Like if I pressed A, how can I send it to the Microcontroller?
Secondly, how do I take the received information from the PC and make an if statement? Like If received info == 'A', LED_ON();?
ThankYou, I am completely new to UART. Also, i would like to give credit to societyofrobots.com for helping me alot(tutorials).
