My examples fir the new Arduino Pro board the Portenta H7 - hpssjellis/my-examples-for-the-arduino-portentaH7. ... (Note: must use protective resistors if using an older 5V arduino). The easier ...

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 ...

That doesn’t mean the Arduino is limited to the capabilities of an ATMEGA328 chip. There are plenty of board variants available, with an entirely different set of features like different ...

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 ...
