Overview
Me Shutter is a special module designed to implement automatic photography for digital SLR cameras. Users can use it to take high-speed photos, or take time-lapse videos and photos with the intervalometer. The blue tag on the interface of this module indicates that it is a dual digital interface, it should be connected to a port with the blue tag on the main control board, and it should be connected to a camera with a dedicated cable.

Pin Definition
The connector of Me Shutter has 4 pins. The features of the pins are shown in the following table.
| SN | Pin | Feature |
| 1 | GND | Connect the ground electrode |
| 2 | VCC | Connect the power cord |
| 3 | S | Control the camera shutter |
| 4 | F | Control the camera focus |
Wiring Mode
● RJ25 cable
The tag color on the interface of the line follower sensor is blue. When you use an RJ25 connector, you need to connect it to a port with the blue tag on the main control board. Take Makeblock Orion as an example. You can connect it to port 3, port 4, port 5, or port 6 as shown in the following figure.
● Dupont cable
When you use a Dupont cable to connect to Arduino Uno, pin S and pin F of the module should be connected to digital interfaces as shown in the following figure.
Programming Guide
● Program with mBlock 5
Me Shutter supports programming with mBlock 5. The following is a brief description of a block on the module:
| Block | Features |
| Select a port Set the function of the module (press shutter, relese shutter, start focusing, or stop focusing) |
● Program with mBlock 3
Me Shutter supports programming with mBlock 3. The following is a brief description of a block on the module:
| Block | Features |
| Select a port Set the function of the module (press shutter, relese shutter, start focusing, or stop focusing) |
● Program in Arduino
If you program in Arduino, you need to use Makeblock-Library-master to control the Me Shutter.
Through Arduino programming, the following program can instruct the camera to take time-lapse photos when the camera receives the corresponding signals.
| Function | Feature |
| MeShutter(uint8_t port) | Select a port |
| void shotOn() | Output a low voltage to the camera shutter |
| void shotOff() | Output a high voltage to the camera shutter |
| void focusOn() | Output a low voltage to the camera focus |
| void focusOff() | Output a high voltage to the camera focus |
The camera can take time-lapse photos with the control of the camera shutter and focus.
