I want to send everything my project Arduino (or ESP32 etc) sends out on the TX pin to another Arduino on my workbench so I can see what's going on - remotely!
Easy enough but there are some caveats if you want to take full advantage of these little Serial Wireless Transceivers. Luckily for us, there are only 5 wires needed: two for power, two for the data and one control wire (which you might not need).
In fact, in my project I'm using just three wires: VCC, GND and TX! So simple. You'll see this module in the opening shots of the video. And you can do this right out of the box if you are happy with the 9,600bps transmission rate.
