Hey Nomad, great video. I can tell you put a lot of work into it. I had an idea for a video. How about making an esp32 with a joystick acting as a websocket server, talking to a websocket client esp32 which is controlling a small robot arm? -Collin
Hi! Thank you so much for watching my video and for taking the time to leave a comment. I'm glad you enjoyed it and appreciate your feedback. Your idea for an WSP32 with a joystick as a websocket server controlling a robot arm sounds really interesting! I'm actually already planning a video on using buttons to control motors, but adding a joystick to the mix would definitely make it even more fun. I'll definitely keep your idea in mind for future videos. Thanks again for your suggestion!
Great video though a bit advanced for me. I have some programming background, but it has been years since I done any server programming. I was hoping this would expand on the esp web server example but add a button for the light and relay. Still, looks good and I like the music though it is a bit louder than it needs to be.
Thank you for watching the video and for your feedback! I'm glad you found the video informative, even though it may have been a bit advanced for your current programming background. I'll keep this in mind for future videos and try to cater to a broader audience. Regarding your suggestion of adding a button for the light and relay to a ESP32 web server generated webpage, while my goal is to provide unique content that isn't widely available on UA-cam, I understand that videos like these may generate higher interest. I will experiment with one such video in the near future and keep your request in mind. In the meantime, if you would like to try combining the ESP32-CAM web server with the relay control from my video, you could use the example code for the ESP32-CAM under File > Examples > WiFi > SimpleWiFiServer and incorporate the relay control parts from my video. If you have any questions about that or any other aspect of the topic, please don't hesitate to ask! I appreciate your support and am glad to hear that you enjoyed the music, although I understand it may have been a bit too loud. I'll definitely lower the volume in future videos to create a better balance. Thank you again for your feedback and for watching, and I look forward to hearing from you again!
Hi Nomadic, I put together a camera using ESP32-cam, and a 5vdc stepdown from a 9 volt battery. Image appears on a webserver. All works well. The problem is that the 9 volt battery dies rather quickly and pushing the button on the 5volt stepdown is not practical. I need a way to control the power going to the camera with a relay connected to wifi, so that the camera only works when i turn it on with my phone, hopefully saving the battery. If there a way to do this using a relay connected to the ESP32? Seems to me that would still use the same amount of current as if the camera was on. How can i turn the camera on or off without using too much power. Thank you so much for your help.
Hi, Thank you for your question. It's great to hear that you've successfully set up your ESP32-cam and webserver. There are multiple approaches you could take to minimize power consumption. I recommend exploring Deep Sleep Mode or possibly lowering the frame rate and resolution of the camera. Using a relay to control the power to the ESP32-cam could work; however, you are correct that this method may not significantly reduce overall power consumption if the relay itself uses a lot of power. A more efficient solution might be to use a solid-state relay or a MOSFET, which consume very little power in comparison. One approach I would consider is allowing the client to send commands to the ESP32-cam to turn the camera on and off. While the module would continue to operate, the power-consuming camera could be deactivated when not in use, thereby saving energy.
Hi! You have to use a step down to 5V to power the ESP32-CAM module. You can do this with eg an LM2596 DC-DC Buck Converter. You can see me using it here: ua-cam.com/users/shortsMjuixQkyk3Y Just browse Amazon for LM2596
Great to hear that you enjoyed the video and thank you for taking the time to provide feedback! I appreciate your support and will take your suggestion into consideration for our upcoming videos. I understand that some viewers prefer to watch content without music, so I will make sure to lower the volume of the music in my future videos. Thank you again for your valuable input, and I hope to continue creating content that you enjoy!
Great video but i do have a problem, why the video is blinking in my program, altough the code is same with you, but i dont have an antena is that a problem why the video is blinking?
The issue with the blinking video stream is likely caused by low voltage, in my estimation. To troubleshoot this, I suggest bringing your device closer to the router and observing whether the problem persists. This will help you determine if the issue is related to a weak connection.
Hey! Thank you for watching! Have you tried running the LCD by itself with your ESP32? Without seeing your code or any additional information about your setup, it seems to me that you might be trying to access an invalid memory address. This could be the case if you have configured the wrong type of LCD in your code. Here are a few more tips to help you troubleshoot: Check Your Wiring: Sometimes, issues arise from simple mistakes in the wiring. Ensure that all connections are secure and correct according to the LCD’s datasheet. Update or Reinstall Libraries: Make sure that you are using the latest version of the library compatible with your LCD. Sometimes, updating or reinstalling the library can resolve unseen issues. Simplify Your Code: Try to simplify your code to the bare minimum required to initialize and use the LCD. This can help eliminate any potential software conflicts or unnecessary complications. Review Documentation: Thoroughly review the documentation for both your ESP32 board and the LCD. There might be specific settings or quirks noted in the documentation that are crucial for your particular hardware setup. Use Example Sketches: Run example sketches provided with the LCD library, if available. These examples are typically designed to demonstrate the correct initialization and usage, which might help you pinpoint what’s going wrong in your setup. I hope these suggestions help! Keep experimenting, and don’t hesitate to ask for more help if you need it.
Compilation error: 'ledcSetup' was not declared in this scope; did you mean 'ledc_stop'?

how do you power ESP 32 cam , if you use 12v battery? you just connected ESP 32's GND to battery..
