Arduino Sony Remote Control

Как собрать и запрограммировать робота на Arduino(Freeduino, Roboduino, Seeduino ...). Используем Wiring и Processing.

Arduino Sony Remote Control

Сообщение frwind » 13 июн 2012, 14:10

Продублирую свои наработки по сбору информации по созданию на Arduino, пульта управления, на базе LANC протокола, для видеокамер Sony
http://86rc89.com/viewtopic.php?f=19&t=987
==================================================================

Во нашол, народ делает пульты к видеокамерам Sony, на Arduino.

* Arduino LANC zoom controller - AKA Zoomduino
* By Angus Findlay
* Using code from Brady Marks of Furious Green Lab
* Connections:
* LANC 2.5mm plug sleeve to Arduino Ground
* LANC 2.5mm plug  ring  to Arduino Vin (input to regulator, NOT 5V)
* LANC 2.5mm plug   tip  to Arduino Digital Pin 2
* Potentiometer   wiper  to Arduino Analog Pin 0
* Potentiometer   outer  to Arduino 5V and Ground, switch polarity to reverse zoom direction.
*                        This provides a voltage divider to determine which code to send the camera.

* This code has only been tested with a Canon XH-A1, and is provided entirely without warranty or guarantee.
* I hope it's useful for people, but if it isn't, I won't be held responsible.

Спаял, работает, теперь надо облагораживать, да на штатив


Сделал дистанку на базе Wii нунчака, джойстиком зумим, кнопками запись и фото.
