Panasonic Shutter Release Cable for Arduino Camera Control and Timelapse Ep 22
Вставка
- Опубліковано 30 тра 2017
- 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);
}

Late to the game, but great video and one of the better ones I have seen on this subject 👍🏻
Made the same circuit back in 2016 with relays like yours but the relays go bad at the most inopportune time. So I looked into opto-isolators that use light to complete the circuit with no moving parts and I never looked back. I use digital pin 13 for the click circuit and I could delay the onset of click by changing the two values of the arduino pin 13 in conjunction with the servo values on pin 7 that drives the slider carriage and pin 8 that drives the pan stepper motor. Everything is powered by a 12 volt deep cycle battery using 9 volt UBEC for the camera and stepper and a 5 volt UBEC for the arduino and servo motor. I'll be producing a video and share this knowledge soon.
You can use transistor switching too. It's not high current or anything. I'm now sure deep cycle batteries are really good if you could just build a power supply to hot swap out something with lithium ion or just plug it in. Too much weight for me. Post a link to your video when it's done.
Great info. Thanks!
Thanks 👍
Thanks for this! Just what I was looking for. I'm only starting to get into Arduino and electrical stuff in general, and I'm currently looking to build a controller for my Nikon camera soon. Would you happen to know if these signals would be the same for Nikon? Otherwise, could you point me in the right direction as to how I can find out the right signals? I've found some for IR but I'm looking for a wired solution, like this. Thanks in advance! Great video.
Great video. Can you help me with my project? I want to make a shoot move shoot,using Optocoupler. I need a schematics of wiring opto to arduino.
Great video! How did you find the specs for the resistance values needed? I'm trying to do something similar but with an audio recorder
It was in a data sheet. Always look for data sheets.
Hi... have you try with PIR Sensor?
Hi! Very interesting video! I'm wondering if, if I just wanted to trigger the shutter remotely, the circuit could be significantly simplified? In fact, I'm wondering if, using a 'cheap' remote release, it could be as simple as making a jumper to the focus pole, and running the wires out the end of the knob to fit a 3.5 stereo mini jack that I'd need in some projects based on in arduino. Thanks in advance and good job!!
You don't need an Arduino. All the camera needs is too see those resistances. I kinda stopped making videos after this. I had a more complex system, but never posted it. That why I even had the Arduino.
@@Sunpixelvideo yeah, sory. You dont need arduino, of course! -but i Want to use arduino, because my question was regarding an arduino system totrigger the lumix remotely -intervalometer, for instance-. The truth is that I did not explain myself very well, my apologies.Thanks for your videoand for your answer! :)
Yeah, sure you can use an Arduino. You could use a potentiometer to set your shot intervals. Probably like ten lines of code to do it. I know I used relays to isolate the voltages. That video was the start of using stepper motors to move the camera and taking shots to get moving time lapses. I lost the disk with the project, but the code wasn't too crazy.
I'm trying to configure a remote cable for my Lumix FZ-1000 for a slider I'm building to do some shoot-move-shoot time lapses. I'm an electronics greenhorn and I am not making any progress with this. I notice you say you have two wires that are useful coming from the camera that supply 3.1V-your black and a green (ground). I found my two wires, but I measure only 1.8V coming from the camera. Would this change the resistor values I need?
Also. I don’t need the auto-focus, so is it possible to activate only the shutter trigger signal?
Thanks for any advice you can give!
I fairly certain the cable is going to be the same for an fz1000, since it's in the same generation of cameras.
I don't use the auto focus either, even though I build that into my own cables. Let me look that up and I post a second message.
I believe you'd be able to get away with a 2k radiator and just have it open, so you could then just have a switch or relay or transistor or whatever close the circuit with the 2k resistor.
If that doesn't work, you'd just have to add the other 39k worth of resistance and skip the center tap for the focus.
THANKS SO MUCH for the reply. I have been fussing with these dang resistor settings for hours and this combo worked!!!!!
Which CuteQueen Resistor Pack do you have? 700, 800, 3325? That looks nice and organized
3325, You have to sort them after they come, but for the same price as Radio Shack charged for 15 resistors, it's worth it.
Will this work for triggering mobile cameras as the selfie sticks do?
Not when the camera is sleeping :)
Tried this with a lumix gx7 but it doesn’t work. No response from the camera when shorting wires
Do you have the correct resistors in the circuit? The camera just sends out a fixed voltage. It then sees that the voltage coming back is some value based on the voltage drop in the circuit. If you don't have those resistors, you'll have a different voltage drop and it won't work. Just speculating what the issue might be. I'd need to see the exact setup to know what went wrong
@@Sunpixelvideo I've set up the circuit correctly I'm pretty sure, I get the same resistances as you do when you're checking for continuity at 4:39 . However, I don't see the voltage that my camera sends out when I test it with my multi meter, it always shows 0. Perhaps my camera model doesn't work in the same way or I have to switch on a setting?
@@gravnine I think ("think") all Panasonic cameras work the same. I think this was on a G7 that I did this. I haven't looked up data sheets in a while, so I'm not sure.
What's your camera model? Maybe I can at least get you some information to help.
@@Sunpixelvideo I got Panasonic DMC-GX7
