Intro: OV7670 Arduino Camera Sensor Module Framecapture Tutorial
Description
The camera module is powered from a single +3.3V power supply. An external oscillator
provide the clock source for camera module XCLK pin. With proper conguration to the
camera internal registers via I2C bus, then the camera supply pixel clock (PCLK) and
camera data back to the host with synchronize signal like HREF and VSYNC. The OV7670
camera module is a low cost 0.3 mega pixel CMOS color camera module, it can output
640x480 VGA resolution image at 30fps. The OV7670 camera module build in onboard
LDO regulator only single 3.3V power needed and can be used in Arduino, STM32,Chipkit,
ARM, DSP , FPGA and etc.

You have to download this to be able to interface this camera sensor module on your
pc.Open the zip le and install to your computer. By default, this will be install to your c
drive in your program les folder. As for mine, it is stored in C:\Program
Files\Java\jdk1.8.0_74. You can refer picture above.
NOTE : This jdk-8u74-windows-i586.rar le is quite big.

Step 4: Sample Source Code
This sample source code is originally from this link
(https://github.com/ComputerNerd/ov7670-no-ram-arduino-uno). Download this sample
source code, open it on your Arduino IDE, connect your Arduino Uno Board to your
computer and upload it. Select the correct board and port before uploading this source
code. Refer image above for help.
NOTE : Don't mind that it does not recognize some libraries in the beginning of the le. If it
bothers you, comment the whole line out with //
Step 5: Checking Your Port

Find out what USB port your Arduino is connected to, something like COM4 or COM5. You
could check it on your Control Panel > Device Manager > Ports (COM & LPT) > right click >
Properties > Port Settings > Advanced > COM Port Number > /Select Your Port Number/.
You can refer the image above for help. As for mine, it is port COM5.

Depending on what port number your Arduino is connected to, download the
corresponding le. COM1 = com_1.rar , COM2 = com_2.rar and etc. Open your com#.rar on
WinRaR, extract/copy the 'code' folder from com_#.rar, go to Local Disk > Program Files >
Java > jdk1.8.0_74 > bin and paste it there. you can refer the picture above for a better
understanding.
Step 7: C:\out
You have to create a new folder on your c drive / Local Disk (C:). This will be your camera
module sensor's taken picture's destination. Name this folder as out (it could be anything
though).

Step 8: Extra.rar
1. Download and extract the Extra.rar le below and open it. As you could see, there is src
folder, lib folder and "win32com.dll". You have to copy and placed "win32com.dll" in the
"C:\Program Files\Java\jdk1.8.0_74\jre\bin" directory.
2. Then, open the lib and you could see the "comm.jar" and "javax.comm.properties" in it.
Copy and paste the "comm.jar" in "C:\Program Files\Java\jdk1.8.0_74\jre\lib\ext" and
"javax.comm.properties" in the "C:\Program Files\Java\jdk1.8.0_74\jre\lib" directory.
NOTE : it may ask for administrator permission, just proceed anyway.

Open cmd and open the folder wherein the code folder is by writing its address. mine is
"C:\Program Files\Java\jdk1.8.0_74\bin". Click enter and it will give u "C:\Program

1. If your cmd cannot nd images, try switching the USB of the arduino from a USB2.0 to a
USB3.0 (blue socket) or vice versa.
2 If you receive scrambles pictures, you need to edit the sample source code. Edit line:
wrReg(0x11, 12); try changing the 12 to 11/10/9/13. Upload it to the arduino and run the
cmd code again.

I made it last night. I already had JDK installed b/c im a software developer but I had the 64bit JDK so when
I did the instructions step by step and then tried to run the jar, it said something like "cannot run 32bit dll in
64 bit environment" so I got the 32 bit version of the latest jdk (just google "jdk 32 bit download" and then
click first link. Then download the first one that says windows x86 and install that when it finishes
downloading. Then you need to re-do this tutorial and any time he says "Program Files" you need to replace
that with "Program Files (x86)" and then it should work.
