Ttl Serial Camera Arduino

Hello and help!

I am trying to use my new TTL serial camera for a project that is due on Thursday. I want to use the motion detect function to activate a servo. I checked the camera and adjusted the settings using the CommTool, and wired the camera to the Arduino, but I keep getting “no camera found.” I checked and redid all my connections; I also checked to make sure I had imported all of the libraries I need. I’m not sure what else to try. A photo of the wiring is attached (the violet wire is TX) and the code is below. Please help! Thanks, Alix

What I am using is a TTL Jpeg Serial Camera connected to digital pins 2 and 3 and an SD Card breakout that connects to digital pins 10 through 13 on the arduino. I have been able to take snapshots with the camera by itself and save them to the SD card but I have not been able to make it work as a part of the whole setup. TTL Serial Camera I am using an Arduino Uno and I am trying to hook up a Camera to the RX and TX input/output. In the code for testing the camera, they use Serial1.begin. Apr 30, 2020 This article is a quick getting started guide for the ESP32-CAM board. We’ll show you how to setup a video streaming web server with face recognition and detection in less than 5 minutes with Arduino IDE.

what is esp32-cam ?

The ESP32-CAM is a small camera module with the ESP32-S chip that costs approximately $10. Besides the OV2640 camera, and several GPIOs to connect peripherals, it also features a microSD card slot that can be useful to store images taken with the camera or to store files to serve to clients.
