On Paper: Discusson on UART One Way Communication

The transmitting microcontroller will output the communication from its TX transmitter pin to the RX pin of the receiving microcontroller. A wire will be connected from the TX of the transmitting microcontroller to the RX of the receiving microcontroller. A button on the transmitting microcontroller will initiate the transmission through the TX pin. The LED on the transmitting microcontroller will serve as an indicator that the push button is working. An LED on the receiver microcontroller will serve as an indication of a successful communication.
