ARDUINO LED PI ON PI HELD BACK BY PI

Hello, this instructable is about Arduino LED Pi On Pi held back by the Pi project.

So essentially it is a decorative slightly retro-looking blinking LED lamp which is in the shape of Pi (LEDs are in the shape of Pi, and it's all Pi theme).

Arduino (in this projects I used Arduino Nano)

18 LED-s

100-ohm resistor

Wires

PCB Board ( I used 5 cm by 7 cm)

Power jack adapter female connector (not necessary if Arduino is powered via USB port)

MDF Board 5cm x 8cm

Screws

Hinge

Popsicle sticks

Superglue

Spraypaint

TOOLS: Soldering iron, solder, pliers (wire cutters), utility knife, drill and drill bits, belt sander (optional, files are also fine, but it is faster with belt sander).

Before soldering this circuit it would be better to test it on a breadboard.

This is the main part of the build (and also coolest, it could be a project on its own). Start by placing Arduino Nano somewhere in the middle of the board, and then arrange LED-s around it to form a Pi but make sure that you place them in the same order (anodes (+) on one side, cathodes (-) on the other side). Then bend the leads and connect all LED cathodes (-) and anodes (+) are going to Arduino pins according to the schematic. And then add a resistor between the LED-s cathode (-) side and Arduino GND.

Spraypaint board on both sides ( Spraypaint that I used had copper-like color)

When the paint dries cover the side where you would like to place the Arduino Pi board from previous steps.

After you carved out the Pi spraypaint it.

This part is pretty straightforward. Arrange popsicle sticks accordingly then glue them in place (I used superglue). And then shape them using a belt sander or files or something else to form a Pi.

The last part in this step is to connect Popsicle sticks Pi with hinge using screws.

Before assembling it all together drill a hole. This hole is for the power supply (not needed if Arduino board is powered via USB port).

Solder power supply cable to Arduino Nano board one wire goes to GND pin, and other wire goes to 5v pin.

Attach Popsicle sticks and hinge Pi to the backside of the MDF board

Attach Arduino Nano Pi Board to the MDF board using screws with spacers.
