An ATMEGA328 acts as the brains of the operation, with a MAX232 attached for level conversion from TTL to RS232 voltage levels. Serial data are received on the hardware TX/RX lines. Eight digital ...

On the Arduino, dedicated digital pins D0 (Rx) and D1 (Tx) are used for embedded serial communication applications. Using pins D0 and D1 other than for data communications will cause an electrical ...

Arduino is probably the first thing that comes to mind for most hobbyists and students when they think about embedded systems. It has certainly gained its name among the electronics community, and in ...

The RS232 interface enables easy connection with the computer or laptop using a USB to Serial connector or to the microcontroller using an RS232 to TTL converter. A 3-pin header also exposes a 1.8V ...
