![]() Sorry if i cant explain myself better and for my poor english.PD: in my opinion the problem is that they are sharing the USB serial, but i dont really know. As you can see im not posting code by now, cause i dont really know what to do. Open the Serial Monitor to take note of the IP address of the Esp32 camera. ![]() 2) if is not grounded arduino start showing data, but ESP32CAM "friezes" (its like arduino start working and dosnt let esp32cam use the serial monitor, but the ESP is still working, for example with firebase or turning leds on/off), in other words its like they cannot use the serial monitor at the same time. Image classification is not something entirely new on the Esp32-cam and. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board. NOTE: On Uno, Nano, Mini, and Mega, pins 0 and 1 are used for communication with the computer. ESP32 CAM Arduino Kits Monitor Snapshot Face Detection Recognition WiFi Bluetooth Camera Module with 128M SD Card(Tutorial) 1. What we used for our prototype is a device with a certain intelligence. For the second application, we must add the PIR sensor to the hardware just described. When i try to see the data in the serial monitor this happen: 1) arduino's reset pin is grounded so arduino just dont send or recibe data and the ESP32CAM show data in the monitor. Step 1: Serial Monitor Basics All Arduino boards have at least one serial port (also known as a UART or USART ), and some have several. To connect Arduino to the camera you need to connect the red wire (RXD) to Arduino D3 pin the brown (TXD) to D2 the gray to the + 5V signal and finally the violet to ground (GND). I tried a lot of codes (for example Hardware serial and software serial) and non of them worked. ![]() You can read from and write to serial ports using this application. So i think if i can succesful program the ESP the wiring diagram is not the problem (even i can use the camera and connect it with Firebase). Monitors your serial port and allows you to read and write to it like you could with Arduinos IDE. ![]() Strangely to correctly program the ESP, the UoT pin of ESP has to be connected to TX of arduino and UoR to RX, otherwise doesnt connect. ![]()
