Install of electronics on body

---

Prepare the following screws and nuts.

M2x20mm
M2 nuts
M3x20mm
M3x50mm
M3 nuts

Setup of Raspberry Pi4

First, make a SD card with the Raspberry Pi OS installed.
Chose the storage size depend on how much you are planning to save movies (1h 320x240 pixel movie requires around 80MB).



Connect SD card to Windows computer through SD card reader.



Download Raspberry Pi imager from official download site (https://www.raspberrypi.org/software/) to your computer.


Run it.


Chose Raspberry Pi OS(32bit).



Chose SD card as the destination (Never chose other storage !).



Click "WRITE" button to start the initialization.



Assemble the case for Raspberry Pi. This instruction will explain with Miuzei Raspberry Pi 4 case.



Insert the SD card into the RasPi.



Prepare M3x50mm screws and nuts.



Fix RasPi using the following holes on the body part. If the holes are too small or need to be different places, use 3mm drill.



Secure screws with nuts.

Install of Arduino UNO

Arduino UNO


Prepare M2x20mm screws and nuts.


Install Arduino using these holes,

Install of switching board

Install with M2x20mm screw. Insert nuts between the PCB board and body part as shown below to prevent direct contact of solder.


Use those holes.




Connect the jumper wires from the switch board to the Arduino.
GND - Ground of the switch board
Ch13 - Ceiling illumination
Ch12 - Infrared LED
Ch11 - Sync signal (if necessary)
Ch10 - Cue LED
Ch3 - Servo



Connect the power cable from the switch board to the GND and 5V output of the raspi.

Equipment of monitor

Fit the 3mm nuts into the hollows of the body.




Thread the M3x50 screws through the nuts and attach the monitor push adapters.



Place the monitor and turn the screw to make the monitor vertically.



Connect the monitor to the Raspi with an HDMI cable (HDMI-Mini to HDMI).



Find the HDMI connector of Raspi here,



You have done the wiring of electronics on the body.
