GVI Digital Remote Control

The GVI Digital Remote Control for DSLR cameras represents an advancement over previous remote controls for the Canon EOS 450D. This remote utilizes the AVR Microcontroller ATmega328 and is programmed using the Arduino IDE. It serves as a tool for photographers to trigger cameras or flashes based on input signals from various sensors. Currently, it only employs sound and light inputs, but there are plans to incorporate additional sensors in the future. The light sensor provides significant signal amplification, making it capable of triggering in low-light conditions, although its performance in bright sunlight has not yet been tested. Resistor R1 is used to adjust the circuit's sensitivity, while R2 manages the gain or amplification of the input signal. The unit is operated via a push button for menu functions and a joystick switch that allows navigation through Up, Down, Left, Right, and Set functions. The remote control settings are displayed on a Nokia 6100 display (132x132 12-bits GLCD) featuring a Philips controller. The LCD driver for this controller is based on documentation available for the Philips PCF8833 controller and the Epson S1D15G00 controller.

The GVI Digital Remote Control circuit is designed to enhance the functionality and usability of DSLR cameras by providing an efficient interface for triggering the shutter or flash remotely. The core of the circuit is the ATmega328 microcontroller, which is a popular choice for embedded systems due to its versatility and ease of programming through the Arduino IDE. The microcontroller processes input signals from the sensors, allowing for real-time responses to environmental changes.

The light sensor integrated into the system is crucial for enabling operation in various lighting conditions. The choice of R1 and R2 resistors is pivotal, as they allow for fine-tuning of the sensor's sensitivity and the overall gain of the circuit. This ensures that the remote control can effectively respond to different levels of ambient light, thereby increasing its reliability in diverse scenarios.

User interaction with the device is facilitated through a combination of a push button and a joystick switch. The push button serves as a menu navigation tool, allowing users to access different settings and configurations. The joystick switch provides intuitive control over the various functions, such as adjusting settings or selecting options within the menu. This design promotes ease of use, especially in dynamic shooting environments where quick adjustments may be necessary.

The visual feedback is provided by a Nokia 6100 display, which offers a clear and concise representation of the current settings and statuses of the remote control. The choice of a 132x132 resolution GLCD with a Philips controller allows for a rich user interface that can display various parameters and information effectively. The integration of the LCD driver, based on established documentation for the Philips PCF8833 and Epson S1D15G00 controllers, ensures compatibility and ease of implementation.

Overall, the GVI Digital Remote Control circuit is a sophisticated solution for photographers seeking to enhance their shooting capabilities through remote operation, with the potential for further expansion and additional sensor integration in future iterations.GVI Digital Remote Control for DSLR camera is a step forward from my previous remote control for Canon EOS 450D.

in the future i will add more sensors. Thislight sensor gives you a huge amplification of the signal and can be use to trigger in the dark of night or in the day time (not tested yet in a very sunny day). R1 is used to adjust the sensitivity of the circuit while R2 controls the gain (amplification of the input signal).
