EXCLUSIVE - RGB Gizmo Electronics Notes and Code (Patreon)

Here are some notes for a simple Arduino project that gives you some lights on the 3D Printed RGB Gizmo. The 3D printed main body can comfortably house various electronic components including an LCD screen, broadboard, Nano and lights. Since my props are mostly for personal display, I use a rather "temporary" setup with jumper wires and breadboard that allows me to adjust things to my fancy. 

On this post, I have attached the Arduino code I composed to control the light and LCD effects.

Here are the parts that you'll need for my install. (I found Amazon listings that are close to my parts, although I suggest shopping around as some of these listings have more than what you need to complete the project)

• Breadboard 
• Arduino Nano 
• LCD Screen 
• Jumper wires 
• LEDs  (3x White or Yellow)
• Resistors 
• Switch 
• 9V Battery 

The basic setup I used involved using an Arduino Nano to control the blinking operation of 3 yellow lights on the front of the Gizmo and a text scrolling effect on the LCD screen. The setup is powered by a single 9V battery with a side-mounted switch to activate the lights.

Wiring diagram

Here is the basic wiring diagram I used. (Note: The Arduino code is attached to this post and requires the LiquidCrystal L2C library  to compile)

Notes and images....

The LCD screen is mounted to the Gizmo Lid using 3mm hex screws. 

The main body has a place to mount the switch to turn everything on and off.

The blinking LED lights are simply glued to the backside of the translucent 3D printed yellow "buttons"
