# Remote Shutter Button for MEMENTO
## Overview
https://youtu.be/XmMB2Dwa66M
## Minimize camera shake
You can build a remote shutter button for the Adafruit MEMENTO camera for taking still photos without having to manually press the onboard shutter switch!
This simple project uses a momentary push button to create an external remote for triggering the shutter button on the MEMENTO camera.
## Focus and capture
Our 3D printed snap fit enclosure houses the button PCB and doubles as a handle so you can take photos without any camera shake.
This button PCB features an on-board JST PH connector making it easy to connect to the MEMENTO camera board.
## Stomp button
The MEMENTO camera code in CircuitPython allows for easy customization allowing you to trigger the shutter in any number of ways.
We can use copper tape on cardboard to create a stomp button!

## Install CircuitPython
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate.
## CircuitPython Quickstart
Follow this step-by-step to quickly get CircuitPython running on your board.
Warning: Make sure you use CircuitPython 9.0.0 final or later. CircuitPython 9.0.0-beta.1 and earlier have a bug that can corrupt the fileystem.
```auto
import storage
storage.erase_filesystem()
```
Your board will reboot after running this.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_esp32s3_camera/)
Warning: As of CircuitPython 9, you'll need to create a folder called "sd" on your CIRCUITPY drive to mount the microSD card, if it's not already there.
[Follow these steps to create the /sd directory](https://learn.adafruit.com/adafruit-memento-camera-board/circuitpython-memento-starter-projects)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
Plug your board into your computer, using a known-good data-sync cable, directly, or via an adapter if needed.
Double-click the **reset** button (highlighted in red above), and you will see the **RGB status LED(s)** turn green (highlighted in green above). If you see red, try another port, or if you're using an adapter or hub, try without the hub, or different adapter or hub.
For this board, tap reset and wait for the LED to turn purple, and as soon as it turns purple, tap reset again. The second tap needs to happen while the LED is still purple.
If you do not see the LED turning purple, you will need to reinstall the UF2 bootloader. See the **Factory Reset** page in this guide for details.
If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!
A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.**
You will see a new disk drive appear called **CAMERABOOT**. Drag the **adafruit-circuitpython-adafruit\_esp32s3\_camera-etc.uf2** file to **CAMERABOOT**.
The **BOOT** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it!
# Remote Shutter Button for MEMENTO
## Code
Once you've finished setting up your MEMENTO with CircuitPython, you can access the code and necessary libraries by downloading the Project Bundle.
To do this, click on the **Download Project Bundle** button in the window below. It will download to your computer as a zipped folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/MEMENTO/PyCamera_External_Shutter_Button/code.py
## Upload the Code and Libraries to the MEMENTO
After downloading the Project Bundle, plug your MEMENTO into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called **CIRCUITPY**. Unzip the folder and copy the following items to the MEMENTO's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
Your MEMENTO **CIRCUITPY** drive should look like this after copying the **lib** folder and the **code.py** file.
## How the CircuitPython Code Works
The code consists of the [Fancy Camera example](https://learn.adafruit.com/adafruit-memento-camera-board/fancy-camera) from the PyCamera library written by Jeff Epler with some minor modifications to add in the external shutter button. The `A0` pin is instantiated as an input and passed as a `Button` object with a `long_press` interval of one second.
```python
pin = DigitalInOut(board.A0)
pin.direction = Direction.INPUT
pin.pull = Pull.UP
ext_button = Button(pin, long_duration_ms=1000)
```
In the loop, the `ext_button` is checked for either a long or short press alongside the shutter button on the MEMENTO. A short press takes a photo and a long press focuses.
```python
pycam.keys_debounce()
ext_button.update()
# test shutter button
if pycam.shutter.long_press or ext_button.long_press:
print("FOCUS")
print(pycam.autofocus_status)
pycam.autofocus()
print(pycam.autofocus_status)
if pycam.shutter.short_count or ext_button.short_count:
```
Otherwise, the code is identical to the Fancy Camera example, leaving all of the excellent functionality in place.

## Circuit Diagram
The diagram below provides a general visual reference for wiring of the components once you get to the **Assembly** page. This diagram was created using the software package [Fritzing](http://fritzing.org/download/).
## Adafruit Library for Fritzing
Adafruit uses the Adafruit's Fritzing parts library to create circuit diagrams for projects. You can download the library or just grab individual parts. Get the library and parts from [GitHub - Adafruit Fritzing Parts](https://github.com/adafruit/Fritzing-Library/tree/master/parts).

# Remote Shutter Button for MEMENTO
## Assemble
## Two button types
Build the remote case version or this alternate cardboard stomp switch. This demonstrates you can craft your own shutter remote with copper tape and a piece of cardboard.
##
## Remote Case
Use 3 Pin JST wires to plug into the MEMENTO.
Measure and cut wires. Add heat shrink tubing to help bundle the wires before soldering cables together.
## Camera Case
Align the MEMENTO board to the cutouts on the printed case.
The camera case exposes the ports so you can plug in external components and additional sensors.
## Tactile Button
Align the nubs on the printed case to the screw holes on the Tactile push button PCB.
Place the printed lid over the case and press fit to the case.
## Tripod screw
An optional 3/8 to 25/20 thread screw fits to attach a tripod.
Use a flat head or the end of tweezers to thread the adapter.
## Cardboard stomp button
Use strips on copper table on a folded cardboard to create a stomp button of any size.
Use Alligator Clips Cables to "connect" to the copper strips.
Plug the other ends of the cables into into the outer two pins of the MEMENTO A0 port. (Polarity doesn't matter here, either cable can plug into either pin).
Then, to trigger the camera shutter, simple "stomp" on the cardboard so the two copper strips make contact with each other.
