ArduMeter photographic incident light meter

ArduMeter photographic incident light meter

Photographers, makers and Arduino enthusiasts interested in building their very own incident light meter for old meterless mechanical film cameras. Sure to be interested in a project published to the Hackster.io website with instructions on how to create the ArduMeter an Arduino incident light meter.

The project uses an Arduino Nano R3 together with a BH1750FVI Digital Light Intensity Sensor Module and 0.96″ 128×64 OLED I2C Display, rotary potentiometer and a couple of breadboards.

“The device is powered by a small power bank, with results displayed on a 0.96″ SSD1306 OLED each time you press the button. The input from the BH1750 light intensity sensor will be calculated into exposure values (EV). I set the incident-light meter calibration constant to 340 (reference). You can set aperture and ISO via two potentiometers. If you plug it on computers you can get more detailed data via serial port. I don’t have the means to test it yet; sometimes the measured values seems to be pretty accurate, sometimes they are quite different from reflective light meters readings on my digital or analog cameras. I used two mini breadboards glued back-to-back. But you can reproduce this on regular breadboards.”
