GirlsGoIT - 3D Printed LED Cloud Lamp - Anastasia & Ana Maria

As soon as we saw cloud-like lamps online, we decided to give it a go and create a similar model, considering its minimalistic and cute appearance and also its low difficulty factor.

Below are the main steps we followed in creating this cloud lamp.

Also, the lamp was created during GirlsGoIT summer camp.

Enjoy!

• Laptop with Fusion 360

• 3D Printer

• 12 colored LEDs (red, green, white)

• Arduino UNO

• Breadboard

• Dupont cables

• Touch button module (capacitative) TTP223

• 220 Ohm resistors (12)

First and foremost, we started sketching our idea on paper, based on some inspiration we saw online. We decided on the sizes of the cloud and on the aproximate placements of the LEDs.

The second step consisted of designing the cloud in Fusion 360 with the following dimensions: 5 cm width, 25 cm length and 18 cm height.

This is a photo of the wiring diagram of the lamp.

Instead of using only white (which seems as the ideal color for a cloud) we went for something a little bit more creative and created a 3-coloured-pattern (red,white,green), with more red on the left, white in the center and green on the right. We also programmed the LEDs to light in different interesting ways, the regime being changed every time we pressed the touch button.

The entire code is written below, but you can also use the link to the code and the wiring in tinkercad: https://www.tinkercad.com/things/7ej1J8ZwiS1-fina...
