@aliarifatAll good now. I have the esp32 working with the IDE and also have the two boards communicating with ESP-NOW.I was going to use two computers...

@thrandell Nice. Where do you source your motorized wheels with encoders?

@zander FYI @imillard @tfmccarthy I see core electronics is in Newcastle, Australia. Might be a good choice if it can read two sensors a...

@bruceg Not sure if @imillard has previewed your earlier post which I thought had good ideas if you were starting this project for the first time.

@imillard I did remember you saying you would be away until mid September. Personally I find text like the one below easier to use than videos. ...

@imillard FYI @tfmccarthyAdded the locking servo. The next step is to duplicate the circuit for the other machine so locking and unlocking by one mach...

@tfmccarthyHaving spent some time reading your code example including your walkthrough html file all I can say is whew! Clearly written by a professio...

@bruceg Essentially that is how I read the workings of the actual machines. However @imillard wants a wireless connection so no wires to communic...

@mike-parsons Eighteen months ago, I hadn't heard of Arduino, and now here I am talking to you about making two ESP32s talk to each other. I ...

@tfmccarthy The purpose of the post was to explain why I don't write C++ programs anymore or have any interest in trying yet again. My interest in ...

@tfmccarthy No I didn't think you were trying to get me to learn more C++ it was a side comment to explaining my limitations regarding reading the ...

@imillard It is unclear to me to what extent you are interested in coding. Your interest is in train models and I guess your electronic know how co...

@aliarifat Yes maybe. Anyway the fix was simple. esp_now_register_recv_cb(OnDataRecv); changed to,esp_now_register_recv_cb(esp_now_recv_cb_t(On...
