Скачать или смотреть Panasonic Shutter Release Cable for Arduino Camera Control and Timelapse Ep 22

In this video, we will create a cable for basic camera control using an Arduino. With this simple proof of concept, we'll be able to trigger our camera for timelapse or remote start and stop. We can also enable a half press focus. The setup will allow for an Arduino based intervalometer that will play nice with other arduino based camera motion control for a slider or pan/tilt head.
This setup will work equally as well on a Panasonic G7, G80/85, GH4, or GH5, as they all use the same remote.

The resistors are .25W resistors with the values of 2k, 3k, and 36k Ohm. The relay I used is just for proof of concept and a solid-state type would be a better and silent choice for a finished product. The cable was chosen almost at random, so just find one that is a 2.5mm trrs (NOT trs).

This is the basic sketch I was using in the video to test functionality:
//start
const int focus = 7;
const int shoot = 8;

void setup() {

pinMode(focus, OUTPUT);
pinMode(shoot, OUTPUT);
}

void loop() {

digitalWrite(focus, LOW);
delay(500);
digitalWrite(focus, HIGH);
delay(1000);
digitalWrite(shoot, LOW);
delay(500);
digitalWrite(shoot, HIGH);
delay(2000);
digitalWrite(shoot, LOW);
delay(500);
digitalWrite(shoot, HIGH);
delay(2000);
digitalWrite(shoot, LOW);
delay(500);
digitalWrite(shoot, HIGH);
delay(2000);
}
//end
