UART- Digital I/O control using serial port

Digital I/O control using serial port using arduino mega

This is a series of simple projects aimed at getting started with Arduino. This will cover most of the important peripherals of the Arduino starting from simple Digital I/Os and serial communication interfaces.

1:UART-Digital I/O control using serial port.

2:UART-Digital I/O control .

3:UART-Digtial thermometer.

4:UART-PIR sensor intruder detection.

In this we are going to see the experiment

Digital I/O control using serial port:

connect the led to pin 13 and power supply 5v and ground.

If the character 'a' is sent as a input display the led turns on and if the character 'b' is sent as a input display the led turns off .
