I can easily use Arduino UNO's pin3( TXD) and pin 4( RXD) to be able communicate with another device using UART on that device.Is it possible to use Arduino Uno so that it can communicate with the device using RS232?Or must I use voltage level convertor?Thanks
Thanks for the reply.I do not need the full ( true) RS232 protocol .Only convert voltage level so that I can connect to a device that has UART available.Or is Arduino 5V ( that RS232 has) tolerant?Thank
