How to connect two Arduino or two ESP32 or Arduino with ESP32 in Wokwi Simulation?
In Wokwi simulation, we can connect Arduino with Arduino, or ESP32 with ESP32, or Arduino with ESP32, using serial communication. Here are the steps:
1. Open this wokwi project: https://wokwi.com/projects/3976868410...
2. Open the same project again as number 1 above, so that on the computer screen, 2 of the same Wokwi projects appear.
3. Run the simulation of the two Wokwi projects, a dialog box will appear asking for the choice of COM port to use. To connect to each other, use a pair of COM ports.

Note: If you don't have a port pair, please install the virtual serial port software, run the software and create a COM port pair (use the keyword “free virtual serial port” on the internet).

4. After the two wokwi projects are connected to a pair of COM ports, press the button on one of the projects, then the LED on the other project should light up, and vice versa. These two wokwi projects are connected via serial communication.

Note: In order to activate this serial communication, we need to add code in diagram.json, especially in the parts section and in the connection section, as follows:

For Arduino:
"parts": [
{"id": "serial","type": "wokwi-serial-port","attrs": {"baud": "9600"}},
"connections": [
["uno:1","serial:RX","",[]],
["uno:0","serial:TX","",[]],

For ESP32:
"parts": [
{"id": "serial","type": "wokwi-serial-port","attrs": {"baud": "9600"}},
"connections": [
["esp:TX","serial:RX","",[]],
["esp:RX","serial:TX","",[]],
