Supplies

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

Step 1: Print the Case

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

You can download my model from this TinkerCad url.

Step 2: Prepare Supplies

Cut wires about 4 inch (10 cm).

Is better idea to use silicon quality wires.

(note: the rule is in cm)

Step 3: Use Your Solder

Pay attention with wire colors and the order:

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

Step 4: Measure, Cut and Weld OLED Display

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

Step 5: Fold With Solder Heat

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

Step 6: Upload Program With Arduino IDE

• 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

If need Digispark ATTiny85 Nano drivers or Arduino libraries,
