ESPNOW RC Car using ESP32| Joystick Remote Control 👌🏻

[@alexfernandesportrai]

Great tutorial as always Sir. I got it working without much effort. I made a mistake in ordering the ESP32 with 30 pins instead of 38. The 30 pin is not breadboard friendly, so I had to get 2 new boards with 38 pins. It was worth it! Thanks!

[@hashincludeelectronics]

This is awesome news 👏🏻. Nicely done ✅ . It’s always good to get the exact components shown in video because those are well tested as per need and it reduces the chances of errors. 👍🏻

every person in the comment were saying error and stuff but i done it in 1 try with 30 pin esp32, i just edited the code a little bit for the 30 pin one and it worked fine with no issues😃

Hey, buddy. I have a question, I hope you can solve it. My problem is that we did all the connection well and the programming well but apparently we did not connect the esp32 receiver to the wifi of the transmitter and that is why it does not work. Will you know how to connect the two esp? or at least how to see if communication is being effective?
