Step by Step DIY Phone Stand With PicoBricks

In this project we are making a robotic phone stand using the Raspberry Pi kit PicoBricks. 

Features:

1. You can get 3D output thanks to 3D STL files.
2. You can control the phone stand with potentiometer.
3. You can see the temperature and humidity of the room on the OLED screen.
4. If you are in a dark environment, you can turn on LED light and illuminate the surroundings.

The following components on PicoBricks were used in the project:

• Raspberry Pi Pico
• OLED Screen
• Temperature and Humidity Sensor
• Button
• RGB Led
• Potentiometer
• Motor Driver
• Servo Motor

In this step, you can download the STL files I shared with you and print them from your 3D printer:

If you want, you can watch our Youtube tutorial video and do all the operations. If you want to do it by reading, you can continue from the article below.

The first thing we need to do is to connect our Raspberry Pi Pico to MicoPhyton. You can find a step-by-step guide for this from this link:

Below I am sharing the codes you need to install on your Raspberry Pi Pico kit PicoBricks. You can install these codes and start using your phone holder directly:
