Here we introduced one OV7670 camera module just purchased online, including the communication of camera module and Arduino UNO, the using ways to take photo via camera module, and so on. This is an Arduino camera module, adopted the Surveillance cameras digital image processing chip-OV0706, specially designed for image acquisition and processing application, based on TTL communication interface, very convenient to connect with Arduino controller, able to read image and data via UART serial port, and then perform some image processing. This is a detailed DIY guide for the OV7670 TTL and UART camera, and you can also download the code from ElecFreaks.

Step 1: General Description

This camera module can perform image processing such as AWB (auto white balance), AE (automatic exposure) and AGC (automatic gain control), for the video signal coming from CMOS sensor. What’s more, in fusion of other advanced technology such as image enhancement processing under low illumination, and image noise intelligent forecast and suppress, this module would output high quality digital video signals by standard CCIR656 interface. OV7670 built-in JPEG decoder supported reatime encoding for collected image, and external controller can easily read the M – JPEG video streams, achieving the camera design of double stream. OV7670 supported motion detection and OSD display function of screen characters and pattern overlay, capable of self-defining detection area and sensitivity.

Step 2: Test OV7670 Camera Module - Needed Tool for Testing

  • Hardware

SD Module

Digital key module

Arduino UNO

Jumper wire

USB cable

OV7670 camera module

  • Software

Camera_VC0706_TEST

Arduino IDE(download it from official website)

Step 3: Hardware Connection

  1. Connect the hardware as the diagram shows.
  2. Physical diagram.

Step 4: Software Use and Code Programming

  1. Firstly download the two files of Camera_OV0706_lib and Camera_OV0706_TEST from the Camera Module Code written by ElecFreaks and then unzip it.
  2. Put the unzipped file of Camera_OV0706_lib into the Arduino IDE folder of Libraries.

  3. Open unzipped file of Camera_OV0706_TEST, and the program the code into UNO. The detailed steps are demonstrated in the pictures.

  4. Click Tools,and then choose the board of Arduino UNO.

  5. Click Tools / Serial Port,and then choose the corresponding COM number.

  6. And then click the button of programming like below in red rectangle, program the code into the UNO board until done uploading appears.

  7. Finally open the monitoring serial port as below in red rectangle.

  8. When the serial port display the data like demonstrated below, you can press the digital keys to take a photo.

  9. If photo was taken successfully, the serial port would be displayed.

Until now, the module testing has been completed. Thanks for reading.

In my ov7670 cam there is no Rx &amp; Tx pins.
<p>The instructions and code seem to be for VC0706 camera and not OV7670. The article mentions OV7670, the code has lib and test folders named after OV0706 and the source code has header file for camera VC0706. This is very confusing.</p><p>OV7670 does not have tx rx pins while VC0706 does.</p>
<p>The instructions and code seem to be for VC0706 camera and not OV7670. ?????</p><p>sir did u test that , is that codes will differ for VC0706 and OV7670 </p>

<p>This camera is not the OV7670 model. It is actually the OV0706 model. It is very Confusing </p>
<p>Yeap. I think it's written for vc0706 not OV0706. OV has more pins not just 4 pins. </p>
<p>Hi I want to ask if there's an available DIY system it's actually a comination of </p>Burglar Alarm using Arduino and PIR Sensor- with SMS Alarm using GSM Module and Camera
<p>Title is OV7670 but instructions are for OV0706. If I am not wrong, your instructable title is wrong. I am confused.</p>
<p>wrong camera model in description. makes me loose time (only comments seem to guide users to better tutorials about the proper model from title) </p>

<p>Is there a way to salvage a camera module from a dash cam and use that? </p>
<p>Hi sir </p><p>This is purushothaman doing Mechanical engineering final year project ,</p><p>I request you to help me to do the QR code scanner using the OV7670 through the Arduino Uno Sir</p><p>Can you ?</p><p>Please Comment as soon as possible. </p>
<p>This camera is <strong>not</strong> the OV7670 model. It is actually the <strong>OV0706 model</strong>. Could someone please fix this to prevent confusion and so people can actually use the instructabe.</p><p>Thanks.</p>
<p>YEAH</p>
<p>hello, </p><p>Do you have any idea of how to connect ov7670 camera with arduino mega !!! plz let me know if you know how to connect it :(</p>
<p><a href="http://www.360doc.com/content/14/0114/16/2340477_345241913.shtml#" rel="nofollow">http://www.360doc.com/content/14/0114/16/2340477_3...</a></p><p>there you can found the solution </p>
<p>No...</p>
<p>Awesome just what I was looking for. I'll be prototyping with the camera this weekend.</p>
<h4><p>This will never work because the OV7670 is not serial (no tx, rx). Or am I missing something?</p></h4>
<p>You're rigth. The module VC0706 has a TX/Rx.</p>
<p>Instruction is good, but this version of camera is expensive for many fans.</p><p>Here an instruction in russian with examples for chipper version:</p><p>http://privateblog.info/arduino-uno-i-kamera-ov7670-primer-ispolzovaniya/</p>
<p>I sleep no longer thinking of the solution ... I need your valuable assistance</p>
<p>Please your help is generating the error &quot;camera not found&quot;, </p><p>when called cam.begin ... I could not continue ... any idea that does not recognize the camera .. the connection is supposedly simple</p><p>arduino camera</p><p>3v3 3v3</p><p>GND GND</p><p>2 D0</p><p>3 D1</p><p>it does not work</p>
<p>There is no pin that named as TX and RX on OV7670</p>
<p>Does anyone have any success about OV7670 via unoR3 or mega? (with SD card)</p>
<p>I agree that these instructions are for the wrong camera ... it is for the VC0706 and not the OV7670. I suggest that one flags the article with the Instructables team for correction.</p>
<p>ok, so the bottom line is: there is no way to connect an ov7670 camera to a mega 2560 r3 and make it capture or transmit a single frame, much less stream video over usb and display on a pc. Or it is a very well kept secret.</p>
<p>Hi, I have the same problem. You can find the pinout for Mega here <a href="https://www.arduino.cc/en/Hacking/PinMapping2560" rel="nofollow">https://www.arduino.cc/en/Hacking/PinMapping2560 </a> </p><p>pins 50 to 53 are MISO, MOSI, SCK, RST</p><p>RX and Tx are pin 0 and 1 </p><p>What I dont know is wich pins are Tx and RX in the camera :D </p>
<p>where to buy ov0706 camera module...</p>
<p>where is the tx and rx on the ov7076 camera?</p>
<p>GND Tx Rx [SV] </p><p><a href="http://www.fut-electronics.com/wp-content/plugins/fe_downloads/Uploads/Serial%20Camera%20Module%20Programming%20Instructions%20and%20Tutorial.pdf" rel="nofollow">http://www.fut-electronics.com/wp-content/plugins/...</a></p>
<p>the very first link, the link for the camera module doesn't have RX / TX pins.. it has 18pins instead..?!?!</p><p>i've been waiting for someone to use this camera module with an arduino.. this setup doesn't connect.!</p>
<p>let me know if you find something please///////</p>
<p>check this out, someone hacked it already... <a href="https://www.instructables.com/id/Arduino-keychain-camera-motion-detect-cam-hack/?comments=all#C472E85I5YB0LDR" rel="nofollow">https://www.instructables.com/id/Arduino-keychain-c...</a></p><p>.</p><p>i have just recieved my cameras, i will be making my own post soon hopefully</p>
<p>hello copper;</p><p>i have found this camera for only $7 <a href="http://www.banggood.com/it/Mini-DVR-808-Car-Key-Chain-Micro-Camera-Pocket-Camcorder-images-p48256-i36273.html" rel="nofollow">http://www.banggood.com/it/Mini-DVR-808-Car-Key-Ch...</a></p><p>ordered, still not arrived. i'm hoping to be able to somehow hack and control it with an arduino. it has a built in SD card and USB port. microphone as well.. someone needs to offer already a $5 simple arduino camera. this is just crazy.. good luck, will let you know if i figure something out. or you can help me control it maybe?</p>
<p>Well, <br>If it is would not be possible to get the connections, it should be considered to take the section away, to avoid people wisting time on it.</p><p>Thank you anyway to ElecFreaks for the try </p>
