ArduCAM now released a ESP8266 based Arduino board for ArduCAM mini camera modules while keeping the same form of factors and pinout as the standard Arduino UNO R3 board. The high light this ESP8266 board is that it well mates with ArduCAM mini 2MP and 5MP camera modules, supports Lithium battery power supply and recharging and with build in SD card slot. It can be an ideal solution for home security and IoT camera applications.
Build in ESP8266-12E Module
11 digital input/output pins, IO ports are 3.3V tolerant
1 analog input(3.2V max input)

Panoramic photograph is a technique of photography, using specialized equipment or software, that captures images with elongated fields of view. It is sometimes known as wide format photography. In order to create panorama photos, you have to take several photos from different view point and stitching them afterwards. There are basically two ways to get these photos, one is to use one camera and shooting from different position, the other is to use multiple cameras and shooting at the same time. The later has better stitching result than the former and requires less photography experience, but more complex hardware equipment.
With the hardware nature of ArduCAM shields especially the ArduCAM-mini and Multi-Adapter board for Raspberry, you can connect multiple cameras to a single Arduino or Raspberry Pi board, even shoot the cameras at the same time. In this demonstration we will use 4 ArduCAM mini 5MP with its adapter board and an Arduino UNO R3 board to create your own panoramas or virtual tours.
In order to get the maxim field of view, we need to mount fisheye lens into the ArduCAM. The lens parameters like optical format, focal length, FOV is very important for stitching software, you can get these information from your lens suppliers. Here is the lens LS-30180 fisheye specification used in this demo, maybe we can use much better fisheye lens to get better photos.
By connecting 4 ArduCAM mini 5MP with the adapter board and the Arduino board, also inserting a microSD/TF into the bottom side of the adapter board card.
Now you can download ready to use Arduino example sketch for multi-camera setups. The example ArduCAM_Mini_5MP_4Cams_TimeElapse2SD_LowPower.ino will start to initialize 4 cameras and the SD card first, and then take 4 photos at every 5 seconds automatically.
It is good news to hear that the Arduino IDE support was announced on the ESP8266 community forum, the source code can be found from . It is more than another Arduino board, but can be thought as a Arduino combined with a WIFI shield. With faster CPU speed and much smaller form of factor, most important the less than $10USD price is more attractive, you are worth to try although there are also some limitations. Setup is fairly simple with downloads for Linux, OS X, and Windows. More detail setup can be found from adafruit guide.
Now ArduCAM ports our camera libraries for ESP8266, you can use the ESP8266 module with ArduCAM modules to take high quality high resolution photos and save to SD card, or even to publish the photos to webpage. In this tutorial we will use ESP8266 arduino board to take photos and publish to webpage.
In order to transfer a photo to webpage, I have to briefly introduce the technology of websocket first. WebSocket is a protocol providing full-duplex communication channels over a single TCP connection. It is designed to be implemented in web browsers and web servers, so it can be used by any client and any platform like PCs, laptops, pads and smart phones. The standard HTTP protocol which is C/S based architecture, a client send a request to a server, the server send the information requested back to the client and close connection immediately. Unlike the standard HTTP protocol, the websocket protocol only use HTTP protocol for handshake stage, and keep the connection open afterward. It allows bi-directional conversation between a browser and the server. Detail websocket description can be found from wiki.
In this demo, we create a websocket server on the ESP8266 arduino borad. It connects to a user defined WIFI router by DHCP, then you can connect to this server via your web browser.
The assigned IP address can be determined via serial monitor message.
Provide you now have the IP address 192.168.1.105 for websocket server, and open the camera_demo.html located in your Arduino\arduino-1.6.5-r5\libraries\ArduCAM\examples\ESP8266\ArduCAM_Mini_OV2640_websocket_server\html folder from your web browser. Change the websocket IP address get from the serial monitor marked in red box in the picture.
Click the “Connect” button, you will see the websocket connection request from the serial monitor. After few seconds, the webpage will notify the successful connection established.
After that you can click the send button to send a websocket message to ESP8266. It will trigger the capture command on the ESP8266 arduino side, and it will send back the captured image and display on the webpage.

Figure 2 shows the block diagram of ArduCAM mini shield which is composed by lens, image sensor and an ArduChip. The lens is changeable and can be mounted by S-mount (M12x0.5) or CS-mount lens holder. The ArduChip uses ArduCAM proprietary third generation camera controller technology which handles the complex camera, memory and user interface hardware timing and provides a user friendly SPI interface.
Single Capture Mode
Single capture mode is the default capture mode of the camera. After issuing a capture command via SPI port, the ArduCAM will wait for a new frame and buffer the one entire image data to the frame buffer, and then assert the completion flag bit in the register. User only needs to poll the flag bit from the register to check out if the capture is done.
Multiple Capture Mode
Multiple capture mode is advanced capture mode. By setting the number of frames in the capture register, the ArduCAM will capture consequent frames after issuing capture command. Note that number of frames should be set properly and make sure do not exceed the maximum memory space.
The JPEG compression function is implemented in the image sensor. With proper register settings to the sensor, user can get different resolution with JPEG image stream output. It is recommended to use JPEG output to get higher resolution than RGB mode, due to the limitation of frame buffer.
Normal Read and Burst Read Operation
Normal read operation reads each image data by sending a read command in one SPI read operation cycle. While burst read operation only need to send a read command then read multiple image data in one SPI read operation cycle. It is recommended to use burst read operation to get better throughput performance.
Rewind Read Operation
Sometimes user wants to read the same frame of image data multiple times for processing, the rewind read operation is designed for this purpose. By resetting the read pointer to the beginning of the image data, user can read the same image data from the start point again.
Low Power Mode
Some battery power device need save power when in the idle status, the ArduCAM offers the low power mode to reduce power consumption, by shutdown the sensor and memory circuits.
Image Sensor Control
Image sensor control function is implemented in the image sensor. By setting proper set of register settings, user can control the exposure, white balance, brightness, contrast, color saturation and etc.
ArduCAM team now are working on different famous open hardware platform, and successfully port the ArduCAM library to Raspberry Pi, Beaglebone Black and STM32 boards. Also we moved our library to github for better maintenance.

This post introduces how to use ArduCAM host application to take high resolution time elapse image with ArduCAM shield. We need the following items to complete this demonstration:
Arduino UNO board
ArduCAM-F or ArduCAM-LF shield
OV5642 camera module with fisheye lens
Arduino example sketch ArduCAM_SPI_OV5642_FIFO_UART.ino
ArduCAM host application
ArduCAM host application is an Windows application which runs in your Windows computer. It is written in Microsoft C# .NET, precompiled execute program can be download from here, source project files can be download from here. Please note that it requires Microsoft .NET Framework 3.5 version to run.
The example sketch ArduCAM_SPI_OV5642_FIFO_UART.ino receives commands from ArduCAM host application then send back image data when capture is done. The ArduCAM host side save the received image binary data into a JPEG file.
With basic knowledge about example and ArduCAM host application, now let’s connect ArduCAM shield to UNO board, attach the OV5642 camera module, then downloading the example sketch ArduCAM_SPI_OV5642_FIFO_UART.ino .
