Background Inspiration and Value Is running eight cameras simultaneously on one Raspberry Pi CM4 hard? Well, the simple answer is ‘no’, as long as you’ve got in hand the Arducam Camarray Synchronized quad HAT. To complete the task, all you need to prepare is just two HATs with 4 cameras for each.

The Future of Machine Learning Is Tiny The future of machine learning is tiny.Tweet From Pete Warden, technical lead of the mobile and embedded TensorFlow group in Google’s Brain team. Machine learning, seen as a part of artificial intelligence, is the study of computer algorithms that improve automatically through experience. Read more…
Some Arducam camera modules use V4L2 kernel camera drivers (What is a kernel driver?), and each of these drivers requires a specific kernel version to work. The thing is, the Raspberry Pi OS updates its Linux kernel regularly, so keeping up with that update will void your previous driver installation. Read more…
Released in March 2019, the NVIDIA Jetson Nano immediately prevailed in the maker community with its desirable price-performance ratio in AI applications. It provides an AI performance of 472 GFLOPs at $99, nearly 20 times greater than a general-purpose embedded board like the Raspberry Pi 4, which is priced around Read more…
Cameras on the Windows Platform If you click the start menu on Windows 10, you will probably find an app called “Camera.” On a laptop, the app shows the built-in front-facing camera with some simple controls, but how would you use a camera on the desktop end? Aside from a Read more…
When it comes to developing a camera-related project on embedded systems like the Raspberry Pi (RPi) or NVIDIA Jetson Nano (NJN), we will take many factors into consideration. To help you better select a camera module, here is a quick start guide from Arducam. Identify the camera interfaces and choose Read more…
In this demonstration, we introduce how to use the ArduCAM shield on the Arduino Yun board. And view captured photos remotely via WIFI connection.

Arduino beginners often face compatibility problems between UNO and MEGA board. The truth is that the UNO and MEGA board are not compatible with each other in some ways, for example, UNO SPI port pins are 10,11,12,13, and I2C port pins are A4, A5, while Mega board SPI port pins are 50,51,52,53, and I2C port pins are 20,21. Actually the UNO and MEGA boards made some changes from the R0 version to the R3 version to make the I2C interface compatible.

The ArduCAM shield has 6 general purpose IOs which can be set as input or output and greatly extend the power for the Arduino board which has limited IO resources. The structure of the IOs in the ArduCAM shield is the same as the one in the AVR chip, it has a direction register(DDR), a input register(PIN) and output register(PORT). In this demonstration, we will illustrate how to set the GPIOs in the ArduCAM shield as an input and use a PIR sensor triggering the shield to start a capture. (more…)
