RS232 Interface Circuit Descreption MAX232 from Maxim Corp. is a line driver IC for RS232 Interface, MAX232_TX and MAX232_RX is connected to Rx and TX pins of UART1 on ATMEGA256. T1Out and R1In is ...

Claimed as easy to use, the E5805A USB-to-RS232 interface can connect up to four RS232 test instruments to the USB port on a personal computer at baud rates up to 230 Kb/s per serial port.

To do so, the Arduino was set up to monitor the BUSY line on the printer’s parallel port, setting the CTS line active whenever the busy line was inactive.

A clever way to consolidate enough power from the TX data and handshake lines on an RS-232C port to run a small circuit. The typical RS232 transceiver interface IC found in many embedded systems ...

Middlesex, United Kingdom—The TDi2 from Radiometrix is a RS232 interface board that combines a TDL2A 433-9 OEM multi-channel wireless modem module (operating at a half-duplex serial data rate of ...

Requisite hardware setup is very simple: just verify and upload the below sketch to Arduino Uno and that’s all! The sketch enables Arduino to receive instructions (which will actually be in ASCII) ...

[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to connect an Arduino to the DS. For testing he’s soldered an IDC plug to the c… ...
