Connecting a HC-12 unit to a PC

Projects General Guidance

Thank you for any help in advance.

I am currently trying to get my Arduino to talk to my laptop, and was recommend to use two HC-12's to do so. With one attached to the Arduino and another one attached to my PC.

However, when I look up videos on the HC-12 all of them just reference using them to talk between Arduino to Arduino and never Arduino to PC. Is it possible to somehow connect a HC-12 to a USB that I can plug into my PC?

I also feel like there has to be a simpler way of wirelessly talking from Arduino to computer (a distance of around 100 ft) but have no idea how.

You need a USB-UART serial converter to interface the HC-12 with a PC USB port. There are many, and it is very simple to do. Example or this one

The set terminal can be left unconnected for normal operation. Take the set terminal to LOW to enter AT mode to change HC-12 operating parameters (baud, power, channel, ... ).

Hello ethannc

Try out bluetooth at this distance.

Thanks for the advice I appreciate it. One other random question, what did you do to make that figure/what software are people using to do mock ups of their Arduino to Bread Boards?

I use ExpressSketch that i downloaded for free years ago. Not sure if it is still free. It was part of ExpressPCB.

There is also the free KiCad (but has a steeper learning curve)

The Fritzing breadboard images are generally frowned upon here, but there is a schematic view that should be more acceptable.

For simple schematics: How to make schematics that you can post.

I am sure that there are more. Hopefully more members will chime in with their favorites.
