06/05/2012 Category: Arduino, Microcontroller, Project, Remote

This mini remote control for DSLR camera is built based on Arduino Microcontroller. Its hardware consists of Arduino Mini Pro, 1.8″ LCD from Adafruit, Rotary encoder with switch, CNY74-4 Opto-isolator chip, 3.5mm Female Stereo Jack. The device uses 1000mAh LiPo rechargeable battery as power source.

The camera remote control features three major modes: Astro – fit for astro-photography, chains exposure with the same duration, Unique – one shot only, and Increment – The next exposure is computed using the current one and a fixed value. On the test screen, user can test focus and snapshot separately.

In configuration bits, user can set sleep time for the LCD, Set day (full color) or night (red only) mode, set a pre-focus delay before the snapshot (to wake up the DSLR after a long time between shots), the mirror lock-up mode which is useful for perfect landscapes, Set intervals 1/100 second to hours and ability to save and restore settings. Knackes, project designer, said that he has tested the remote (previous version) by took 6 hour continuous shooting with a smaller battery and power to spare.
