![]() ![]() The techniques are exactly the same for any UART to UART device. In these examples I am using Arduino Nanos but any kind of Arduino can be used and for this series I am using Arduino to Arduino communication. ![]() The LED has only two states so simple control codes can be used and to start I am using 1 of on and 0 for off. Controls to turn the LED on or off will be sent via serial from the first Arduino to the second Arduino. We will have one Arduino controlling an LED on a second Arduino. With this is mind for a first project let’s create a simple blinking LED. In the last post I briefly talked about different data formats and how I recommend keeping things as simple as possible. ![]()
