You need this supplies:

• 3d printer with PLA filament
• Solder
• 4 x wires (red, yellow, green, black)
• 1 x 0.91"OLED Display i2c type OLED
• 1 x Digispark ATTINY85 Lilypad Nano Lilypad

Print the case with 3d printer. Using PLA filament.

You can download my model from this TinkerCad url.

Cut wires about 4 inch (10 cm).

Is better idea to use silicon quality wires.

(note: the rule is in cm)

Pay attention with wire colors and the order:

• Green to pin "P0"
• Yellow to pin "P2"
• Red to pin "5V"
• Black to pin "GND"

Cut wires and strip, weld cables same order and put covers to close the device

Close solder to middle of frontal cap and apply hot. Fold carefully. Don't overheat the PLA plastic. Be patient :)

• Unzip attached file PersonaProject.rar
• Open Arduino IDE
• Open the PersonaProject.ino file who is located into the PersonaProject folder
• Set board to Digispark (default - 16.5mhz)
• Compile&send
• Enjoy
