“Build a simple shutter speed tester for film cameras.
This is a project to build a simple shutter speed tester for film cameras.
Classical film cameras have a mechanical shutter that doesn’t require a battery. However, film camera shutters that have not been used for many years may not work properly. The Shutter Speed Tester checks if the shutter speed of the film camera is correct.
The shutter Speed Tester uses Arduino as the main controller and the phototransistor as the light sensor to capture the light transmitted by the flashlight behind the camera body. The captured shutter speed is shown on the SSD1306 OLED display.”
