The second "Socket B" connector differs only slightly from the first in that it has an I2C bus exposed. That last pin is used by the Nano to determine which sensor is attached and helps to prevent accidental misconfigurations. The first socket, called "Socket A," exposes power, GPIO pins, and an ID pin. The primary PCB houses the Arduino Nano, an unregulated 24V input jack, an unregulated 7-12V input jack, a mini buck converter for knocking down the voltage to 5V, and a wide assortment of connectors. Lastly, he created three sensors for taking the readings and sending data back for processing. Next, a 20x4 LCD screen was added so that users could select different options via a keypad and then see the results immediately. At the center is an Arduino Nano-compatible board which runs the firmware for controlling the sensors and display. ARDUINO CAMERA KIT SERIESTo meet the stated goals, srozum began by gathering a series of components for his device. His design included measurements for exposure time/strengths, data averaging over multiple trials, automatic sensor detection, an accuracy of 10 microseconds, and a range of speeds from one second down to 1/8000th of a second. It's a great camera for Arduino centered image recognition projects, because 30W pixel wouldn't be overwhelming for Arduino, so that real-time image recognition is possible. ARDUINO CAMERA KIT SERIALIn order to capture all of this data in an accurate manner, GitHub user srozum set out to build a DIY testing rig that could collect light readings, perform calculations based on certain parameters, and then present it to the user - all while using inexpensive parts and being open source. Grove - Serial Camera Kit includes one control board and two interchangeble lenses, one is standard lens and the other is wide-angle lens. All of these measurement points are vital for calibrating the timers and shutter of a film camera which can create a more realistic image. Alternatively, exposure values can be found by utilizing light accumulation methods that see how much light falls on a sensor over a known window of time. Oftentimes, testers for this camera technology consist of time counting methods which use a light source and a detector to do everything from measuring shutter speed to determining how long it takes for the flash to activate. With the explosion of digital cameras, the equipment required for taking care of film cameras had gradually decreased and/or become more expensive.
