The RS-232 standard also defines lines that indicate whether the receiving device is ready etc., but I won't be using them. To send characters to the display, you simply issue a print() command via ...
There are ways to use Arduino as TTL converter. For instance, you can remove Atmel chip from your board (if it's not soldered) or connect RST to GND. However none of that has worked for me to connect ...
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 ...
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 ...
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 ...
