There are no programmers for ESP32. It only accepts Serial upload over bootloader.
Versions of IDE before 1.8.13 displayed programmers for all board support packages, that is why a programmer could be selected. Now only programmers for package of the selected board are available. But programmers are used only with the "Burn bootloader" or "...
Yes, you will have to change the code to match the Mega pinout.
Because the program need to run quite fast, and the Arduino functions
digitalRead() and digitalWrite() are dead slow, the author of the
program used direct port access for performing the raw IO.
//Wait for vsync it is on pin 3 (counting from 0) portD
Solution for if this occurs on a known working ESP-32-cam with PSRAM (i.e. example sketch with face recognition works ok).
If you're using anything other than PIX_FORMAT_JPEG, try reducing xclk_freq_hz.
In my case, it suddenly worked fine with PIX_FORMAT_RGB888, FRAMESIZE_VGA and xclk_freq_hz = 5000000 (4x lower).
( @Vraj P, this might not apply directly to ...
You need either a memory extension for your UNO - projects like Arducam did this way back 2016 and then used an OV2640 module. If you want to develop something yourself these are the steps (hurdles) to take:
Get a datasheet of the camera
Design a circuit including
plug for Camera and a
memory module (min 512Kb)
Attach it to the UNO
Write a library/...

It is doubtful as bare image sensors usually require specialized software drivers to be of any use. Also, a common Arduino does not have the power to do image processing. Only the few Arduino's built with unusually powerful processors could handle image processing. But, at ...

Check the following:
Your USB cable. Some cables are just plain cheap and can't supply the power the ESP32 needs. Get a better one.
Some PCs are not able to supply enough power from their USB ports to supply the ...
I ran into this issue with the same setup. This Github issue seems identical to ours, and applying the fix in this comment quickly resolved it for me: https://github.com/espressif/arduino-esp32/issues/5128#issuecomment-851785970. Good luck!
According to the schematic and pin notes, I don't think you can use GPIO4 as an ADC input (it can be used as a GPIO pin and technically it can be configured as an ADC pin), but it has a 47k pull-up resistor on it, making it not possible to be used as an ADC input.
Depend on your hardware wiring skill, one alternative is to use an external ADC chip with i2c ...
The limit isn't the camera - it's the memory.
At 3 megapixels you have 3145728 pixels. At 3 bytes per pixel (8 bits each of red green and blue) it requires 9437184 bytes to store the image. That's more than can fit into the 8MB PSRAM.
1600x1200 will probably be one of the standard resolutions that the specific camera in use can capture, and is probably the ...
That video shows a Bluetooth connection between the smartphone and the Arduino.
(A USB connection between the smartphone and the Arduino might be better in some ways).
If you want more information after watching a video like this, click the "show more" button underneath the video to see the details.
Those details clearly say "The Nexus S device ...
With those technologies you have no chance. They are both low-bandwidth devices suitable for sending small amounts of sensor and control data. They can in no way be used to send video data. Both devices are rated in the kilobits or (at most) hundreds of kilobits. For video you need tens or even hundreds of megabits (depending on resolution and compression)....
Look I've just had that problem for a month and if you're using esp32- ov2640 look the camera reference because the one I've had was TY 0V2640-V2.0 and what I've saw it's like a cheap copy of the normal camera, so be careful. I had to buy a new one because everything looked like a broken image, although all the config worked fine. Even changing the ...
One possible cause is given here (scroll down to find this specific issue)
There appear to be two sets of ESP-32-CAMs, one with and one without the PSRAM.
I had tried and tried to get the camera working. However, I decided to concede to the part of me that thought it was a hardware error. I purchased a new OV2640 module and instantly it worked.
I think I learned my lesson in purchasing cheap components. I inspected the old one further. Turns out there was a faulty ribbon cable. Anyways, I hope you aren’t in ...
You could try using the most common solution for streaming low latency drone video, called FPV. You basically connect an AV video output from a camera to a transmitter and use a receiver on the ground to receive the AV video. After this you can connect it to any AV display (or a usb AV decoder if you want to use a computer) and you'll get an almost real time ...
It may be that one of the included libraries (software) you are using depends on pin 3 (E32_RST) of the ESP32 going low in order to operate as expected (wake up and take a picture). Using an alternate pin may wake up the ESP32 but may not behave as expected.
This schematic of the ESP32 Camera shows how switch K1 is connected to pin 3 ...
Detecting a phone could be easily done by capturing WiFi probe requests which are sent by phones having at least one saved WiFi network. Note that such requests alone are often enough to identify the person, if their home WiFi SSID is set to something like "Davids_wifi".
Software-wise, this would be much easier to do on Linux (think Raspberry Pi or a ...
You cannot. The TX and RX lines are UART. UART is not USB. USB is a very complicated protocol, and you need a proper understanding of how it works. It's not a simple serial protocol like UART.
Add to that the fact that the Arduino can in no way handle the amount of data involved in video, and you're already on a non-starter.
As rightly pointed out by others and @JRobert, its very difficult or nearly impossible to live stream a video/audio through Arduino Uno which uses Atmega328 micro-controller which is mostly used for simple embedded processing such as sensor reading, serial tr/rx, i2c like operations.
But there are some workarounds which can make it possible by using some ...
The Uno is a very limited platform, perhaps surprisingly, given its wide range of abilities and built-in hardware features. The two most glaring limitations for you application are its 16MHz clock speed (relative to modern desktop processors) and thus its bandwidth, and it's non-expandable 2KBytes of RAM.
Image processing would be right out the window, and ...
In this specific OV2640 module, it's supposed to have a 12MHz oscillator in the board connected to XLCK pin (you can all time adjust the PLL trough SCCB interface as usual). Remove the plastic lens and see near the CMOS.
