Hi, First, my apologies is this has already been asked, I searched this forum but I could not find anything along these lines. My computer does not have a serial port, and I have a device that has a serial port that I want to connect to my computer. I was wondering if it was possible, since the co…

Connect a jumper from RESET to GND. Your Uno is now a TTL-serial-to-USB converter. TX, RX, and GND are the connections.

What sort of serial signal do you need? If it's a device designed to plug into an external serial socket, it's probably using RS232 signaling. In that case I'd have thought your best bet was to buy a USB-to-RS232 converter - your UNO can't output RS232 without additional hardware.

your UNO can't output RS232 without additional hardware. It can't accept RS232 as input, either.

I am not sure what type of serial communication it is, but I know I only need a Tx, Rx and a ground from my device to my computer. I used a jumper to connect the reset and the ground pin together as suggested and the Rx light flashed when I send the board some text from HyperTerminal, but I was not…

Swap the rx and tx, since the labeled rx and tx is of the 328p not the atmega8/16u2 So put rx of the arduino to rx of the board and same with tx and it will work

Friends I have some doubts with this. I use 3dr radio module for my Copter. The air module has serial port connected in Pixhawk flight controller and ground module has usb port connected in my Windows 10. I tried to connect them using mission planner. Both were loaded settings in the MP but not conn…
